Abstract

Provided are: a light diffraction layer laminated sheet which enables easy production of a card that has a light analysis structure; and a card. A light diffraction layer laminated sheet material which forms a part of a laminated structure of a card by being laminated on top of a card base material. This light diffraction layer laminated sheet material is provided with: a transparent sheet layer; a hologram layer that has a contour smaller than the contour of the transparent sheet layer and is laminated on one surface, which is the upper surface, of the transparent sheet layer; and an HS layer that bonds the transparent sheet layer and the hologram layer with each other.
