The positional relationship between the electrode and the second and third electrodes provided on the back side of the glass is determined by the manufacturing process of heating, sautéing, and heating (the printing process or firing process of the first electrode on the glass surface, and the second and third electrodes provided on the back surface of the glass). Since the process of printing the electrodes on the back of the glass in step 3), the assembly worker only needs to attach the flexible printed circuit board to the back of the glass, and the quality of the input sensitivity is not affected by the assembly process.

１２へ出力される。The operation of the input device with the above configuration will be specifically explained. Now, consider a case where a person's finger is not touching the first electrode 6. When a pulse voltage is applied from the drive circuit 11 to the second electrode 7, a corresponding output pulse is output from the third electrode 8 to the detection circuit 12.

るものである。Therefore, if the reference voltage is set within the range of change of the output pulse, it is possible to determine whether a person's finger has touched the first electrode 6 based on the magnitude relationship between the output pulse and the reference voltage. Here, the quality of the input sensitivity is determined by the size of the variation range of this output pulse, and the size of this variation range is determined by the material and plate thickness of the horizontal channel 9. When the area of each of the electrode 7 and the third electrode 8 is determined, it largely depends on the facing positional relationship of the first electrode 6, the second electrode 7, and the third electrode 8. Therefore, in the conventional method of assembling an FPC on which a second electrode and a third electrode are formed by bonding it to a panel, it is difficult to assemble the FPC with the first electrode facing the second electrode and the third electrode. Even if the assembly worker puts a lot of effort into assembling the parts, the positional relationship will still vary widely and the input sensitivity will be unstable. However, according to the configuration of this embodiment, since the first electrode 6, the second electrode element, and the third electrode 8 are formed in advance so as to face each other on the front and back sides of the touch panel 9, variations in the facing positional relationship can be avoided. It turns out that it doesn't exist. The assembly error is on the back of touch panel 9 [nl is FPC1]
It is only necessary to bond the parts 3 together using the anisotropic conductive member 14. Here, the anisotropic conductive member 14 is a member having conductivity in only one direction, and is connected to the conductive pattern of the touch panel 9 and the F
This allows the conductive pattern of the PC 13 to be electrically connected.

The second and third electrodes opposite to the first electrode provided on the surface of the touch panel can be formed on the back surface of the touch panel by printing, etc., so there will be no variation in input sensitivity during the assembly work process. Transmission of electrical signals between the second electrode and the third electrode and the control board can be easily achieved by simply bonding flexible printed circuit boards together via an anisotropic conductive member.
