て樹脂バンクの発生を抑制することができる。In the method for producing an embossed sheet by irradiation with ionizing radiation of the present invention, the ionizing radiation curable resin on the surface of the base sheet is irradiated with ultraviolet rays to be semi-cured, and then the ionizing radiation curable resin is wound on the peripheral surface of the embossing die roll. Attaching, is an embossing sheet manufacturing method of irradiating and curing with an electron beam, the liquid ionizing radiation curable resin, at the time of introduction between the embossing die roll and the press roll, the ionizing radiation curable resin, , With or without fluidity, it is introduced to the space between the embossing die roll and the press roll in a semi-cured state where it is hardened to some extent, especially in the semi-cured state where the portion relatively close to the surface layer is hardened By comparison, the generation of resin banks can be suppressed.
