Optical card with ic


(57)【要約】 【目的】 カード基材の厚みより厚いICモジュールを 光記録面と反対側に埋め込んだ場合に視覚的に劣らない ようにする。 【構成】 透明保護層5の裏側に光記録部1が設けら れ、この光記録部1を覆ってカード基材4が前記透明保 護層5と積層されており、前記光記録部1以外の領域に てカード基材4の裏側から形成した凹部6にICモジュ ール2が埋設されているIC付き光カードにおいて、凹 部6の底面とICモジュール2の間に隠蔽層3を積層す る。光記録面側から見た時にICモジュール2の背面が 隠蔽層3によって隠れるので見苦しくなくなる。
PURPOSE: To prevent the debasement of the appearance at the time of burying an IC module thicker than a card base material on the side opposite to the optical recording face. CONSTITUTION: An optical recording part 1 is provided on the rear side of a transparent protective layer 5, and a card base material 4 and the transparent protective layer 5 are laminated to cover this optical recording part 1, and an IC module 2 is buried in a recessed part 6 formed from the rear side of the card base material 4 in an area other than the optical recording part 1. In this optical card with IC, a concealing layer 3 is laminated between the bottom of the recessed part 6 and the IC module 2. Since the back face of the IC module 2 is concealed by the concealing layer 3 when viewed from the optical recording face side, it is not unsightly.
