There is provided an IC card having a plane coil in which a short circuit is seldom caused by the deformation generated by an external force given to the plane coil in the traverse direction. An IC card comprises a rectangular plane coil formed by punching or etching a thin metallic sheet in which a conductor line is wound a plurality of times on substantially the same plane, wherein terminals at both ends of the plane coil and electrode terminals of a semiconductor element are electrically connected with each other, and a bent portion composed of a curved portion in which the conductor on each winding composing a linear portion of the plane coil is curved at the substantially same position in the same direction is formed in the conductor on each winding of the plane coil
