Abstract: A contactless communication medium includes a film base, an antenna coil disposed on a top surface of the film base and formed in a rectangular spiral shape, an IC chip performing wireless communication processing via the antenna coil, first plate electrodes connected to an inner end and an outer end of the antenna coil, and second plate electrodes disposed on a rear surface of the film base so as to be opposite to the first plate electrodes in the thickness direction of the film base. The first plate electrodes and the second plate electrodes have a first electrode portion and a second electrode portion respectively extending along a long side direction and a short side direction of the antenna coil so as to be adjacent to an inner periphery or an outer periphery of the antenna coil when viewed perpendicular to the film base.
