An IC card is provided into which information can be written without requiring a writer. The IC card ( 1 ) includes an IC chip ( 3 ), an antenna ( 4 ), and a plurality of circuits ( 5 ), which are built into a card main body ( 2 ), terminals ( 6, 7 ) connected to the extremity of each of the circuits ( 5 ), and a conductive sticker ( 8 ) affixed to the surface of the card main body ( 2 ) and providing continuity between the terminals ( 6, 7 ). Among a plurality of the conductive stickers ( 8 ), by peeling off a particular conductive sticker ( 8 ), continuity of the circuit ( 5 ) corresponding to the peeled conductive sticker ( 8 ) is broken, and since the IC chip ( 3 ) transmits a signal corresponding to the continuity/discontinuity states of the plurality of circuits ( 5 ) to a reader, information can be written without requiring a special writer by simply peeling off the conductive sticker ( 8 ), thus greatly improving the convenience.
