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 10 comprises a rectangular plane coil 14 formed by punching or etching a thin metallic sheet in which a conductor line 12 is wound a plurality of times on substantially the same plane, wherein terminals at both ends of the plane coil 14 and electrode terminals of a semiconductor element 16 are electrically connected with each other, and a bent portion 20 composed of a curved portion in which the conductor 12 on each winding composing a linear portion of the plane coil 14 is curved at the substantially same position in the same direction is formed in the conductor on each winding of the plane coil 14.
An IC card comprising a plane coil formed by punching or etching a thin metallic sheet in which a conductor line is wound a plurality of times on substantially a 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 curved portion protruding inward and/or outward with respect to the plane coil is formed in the conductor line on each winding composing the plane coil in a position such that the curved portion does not overlay or surround the semiconductor element.
An antenna for an IC card having a plane coil, formed by punching or etching a thin metallic sheet, in which a conductor line is substantially wound by a plurality of times on a same plane, wherein a curved portion protruding inward and/or outward with respect to the plane coil is formed in the conductor line on each winding composing the plane coil in a position such that the curved portion does not overlay or surround the semiconductor element.
