    • This invention provides a non-contact type IC card that can prevent electrostatic discharge failure of an IC chip caused by static electricity generated in a metal reflective layer. In a non-contact type IC card, an inlet sheet on which an antenna and an IC chip connected to the antenna are mounted is embedded in a card base member and a metal reflective layer (which corresponds to a hologram-magnetic recording layer) is laminated on the surface of the card base member. The non-contact type IC card includes conductive members that are embedded in the card base member. The conductive members attract static electricity generated in the metal reflective layer, and discharge the static electricity from a second surface of the card base member (the surface of the card) opposite to a first surface of the card base member (the back surface of the card) on which the metal reflective layer is laminated.
    • 本发明提供一种能够防止由金属反射层产生的静电引起的IC芯片的静电放电故障的非接触型IC卡。 在非接触型IC卡中,安装有与天线连接的天线和IC芯片的入口片被嵌入卡基部件中,金属反射层(对应于全息磁记录层)为 层压在卡片基材的表面上。 非接触型IC卡包括嵌入在卡片基件中的导电构件。 导电构件吸引在金属反射层中产生的静电,并且从卡底座部件(卡的表面)的第二表面排出静电,该第二表面与卡片基件的第一表面相反 卡),其上层叠有金属反射层。
