Abstract
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.
