An IC card comprising: a first sheet member; a second sheet member; and a core
layer fixed therein an electronic part by an adhesive agent and provided between
the first sheet member and the second sheet member. The electronic part comprises
an antenna coil formed by an antenna wire and an IC module comprising an IC chip.
The antenna wire has a structure represented by following General Formula 1,
wherein Antenna Shape X1 represents the cross sectional width of the
antenna wire being parallel to the surface of the IC card; Antenna Shape Y1
represents the cross sectional width of the antenna wire being perpendicular
to the surface of the IC card.
