Abstract
An optical card including a card substrate having a recess, and an optical recording member including, in the following order, a surface hard layer, a transparent protective layer, a pattern layer, and an optical recording material layer. The optical recording member is embedded in the recess through an adhesive layer so that the optical recording material layer is in contact with the adhesive layer. The end face of the optical recording member and the side face of the recess of the card substrate respectively have particular tapers facing each other. The optical recording member is embedded in the recess of the card substrate so that the end face of the optical recording member is not exposed from the card substrate.
