发明名称 Non-contact type IC card
摘要 There is provided a non-contact type IC card that prevents electrostatic discharge failure of an IC chip embedded in an IC card. A non-contact type IC card includes at least a magnetic recording layer, a metal reflective layer, and a hologram layer, which are sequentially laminated on a card base member, and an antenna and an IC chip connected to the antenna that are embedded in the card base member. The metal reflective layer is made of a material of which electric conductivity is smaller than 28.9×106/&OHgr;m, or is composed of a thin film of which surface resistivity is 7.02 (&OHgr;/□) or more.
