Film-like electrode connectors such as those shown in Japanese Patent Publication No. 713 and film-like electrode connectors for Rochromic Display (ECD), and thermosetting adhesive layers as shown in Japanese Patent Application Laid-open No. 59-19] and No. 210, There is an adhesive conductive sheet formed by forming a flexible organic film over the entire surface and forming conductors on the adhesive layer in the same arrangement as the bonded portion of the adhered object. Furthermore, there is also a conductive rubber connector made of metal particles having a diameter of about 15 μm uniformly dispersed therein.
ところが、前二者は−ＬＴＩ体の接Ｖεを行うことかで

なうことになり、信頼性に欠ける。又、ＩＴ○（透明電
極）等のように合金のできない電極では金属粒子が接触
しているだけで融合しておらず信頼性が低い。However, the former two methods can only connect the -LTI body to Vε, and in the case of an adhesive conductive sheet, the conductor portion has no adhesive force and is unstable. Furthermore, in the case of a conductive rubber connector, it is possible to connect the upper and lower conductors, but since it is a type in which fine metal particles are dispersed, fine metal particles in unnecessary areas impair insulation, resulting in a lack of reliability. Furthermore, in electrodes that cannot be alloyed, such as IT○ (transparent electrode), the metal particles are only in contact but not fused, resulting in low reliability.
目的
本発明は、このような点に鑑みなされたもので、導体部

異方性導電シートを得ることを目的とする。Purpose The present invention has been made in view of the above points, and provides a unique structure that allows the shape of the conductor portion to be arbitrarily arranged and formed, and also allows the conductor portion to have adhesive strength to connect the upper and lower conductors with high reliability. The purpose is to obtain a directional conductive sheet.

特徴とするものである。Structure In order to achieve the above object, the present invention provides a tape having releasability in which a thermoplastic conductor portion made of metal particles, a thermoplastic resin, a tackifier, and a solvent is formed by screen printing, a thermoplastic resin, and an adhesive. A tape having mold releasability formed with an adhesive layer consisting of an imparting agent and a solvent is submerged, and the thermoplastic conductor portion of these tapes and the adhesive layer are placed facing each other and heated and pressed with a heat roller. The thermoplastic conductor portion is formed at a predetermined position of the adhesive layer.

０μｍ程度となる。Hereinafter, one embodiment of the present invention will be described based on the drawings. First, as shown in FIG. 2, a tape 1 having releasability is prepared, and a thermoplastic conductor portion 3 is formed in a desired pattern on this tape 1 by screen printing using a screen printing device 2. This thermoplastic conductor portion 3 has a particle size of 0.1 to 1
It is composed of metal fine particles of about 0 μm, a thermoplastic resin, a tackifier, and a solvent. The thickness of the second thermoplastic conductor portion 3 formed on the tape 1 after drying is 20 to 3
It is approximately 0 μm.

is prepared, and an adhesive layer 6 is coated on the surface of the tape 4 while being conveyed by a plurality of rollers 5. This adhesive layer 6 is a hot melt adhesive having a softening point lower than that of the thermoplastic conductor portion 3, and is composed of a thermoplastic resin, a tackifier, and a solvent. The thickness of this adhesive layer 6 formed on the tape 4 after drying is 10 to 20
It is about μm.

置に一体化されることになる。As shown in FIG. 4, these tapes 1 and 4 are conveyed while being heated and pressurized by heat rollers 7, conveyance rollers 8, etc., so that each thermoplastic conductor portion 3 and adhesive layer 6 are in opposing contact with each other. . Here, the heat roller 7 applies pressure while heating at a temperature above the softening point of the adhesive layer 6 and below the softening point of the thermoplastic conductor portion 3. As a result, the unsoftened thermoplastic conductor part 3 is conveyed in a state where it bites into the already softened adhesive layer 6 by the heat roller rough, and the thermoplastic conductor part 3 is integrated into the adhesive layer 6 at a predetermined position. That will happen.
そして、最後に離型性を有するテープ１．４を剥がすこ

で、取扱いが容易となる。First, it can be seen that with the anisotropic sheet 9, it is possible to connect the upper and lower conductors. In this case, the position and shape of the thermoplastic conductor portion 3 can be formed arbitrarily by screen printing. In this way, the thermoplastic conductor portion 3 is placed in any desired position and shape, and the metal fine particles are not dispersed over the entire surface, so that insulation of unnecessary portions can be ensured. Further, since the thermoplastic conductor 113 itself has adhesive strength, a reliable connection can be made and the reliability is high. Furthermore, since it is formed into a tape shape as an anisotropic conductive sheet, it is easy to handle.

るものである。Effects Since the present invention is configured to have a J-speed, the shape and position of the thermoplastic conductor can be arbitrarily determined by screen printing and positioned on the adhesive layer to provide anisotropy only in necessary parts. Therefore, the insulation of unnecessary parts can be ensured, and since the thermal conductor/plastic conductor part itself has adhesive strength, a reliable connection can be made with high reliability.Furthermore, the tape Since it is shaped like a shape, it is easy to handle.
