IC CARD AND INLET

PROBLEM TO BE SOLVED: To attain an IC card that mounts two antennas, a dual IC chip and a contactless type IC chip, and has an excellent communication distance with communication frequencies of two IC chips close.SOLUTION: An IC card has: a base material 11; a first coil pattern 12 that is formed in the base material to have both ends connected to a first terminal pair 16; a second coil pattern 32 that is formed in the base material to have both ends connected to a second terminal pair 36; a dual IC chip 1 that has contact terminals 7A and 7B, is mounted so as to connect to the first terminal pair, and performs contactless type communication using the first coil pattern and performs contact type communication using the contact terminal; and a contactless communication IC chip 2 that is mounted so as to connect to the second terminal pair, and performs contactless type communication using the second coil pattern. The contactless type communication using the first coil pattern and the contactless type communication using the second coil pattern are configured to be independently performed in the same communication frequency band, and one of the first coil pattern and the second coil pattern is configured to be formed on an inner side of the other thereof. 【課題】２つのアンテナ、兼用ＩＣチップおよび非接触型ＩＣチップを搭載し、２つのＩＣチップの通信周波数が近く、良好な通信距離を有するＩＣカードの実現。【解決手段】基材11と、基材に形成され、両端が第１端子対16に接続される第１コイルパターン12と、基材に形成され、両端が第２端子対36に接続される第２コイルパターン32と、接触端子7A,7Bを有し、第１端子対に接続するように搭載され、第１コイルパターンを利用した非接触式通信および接触端子を利用した接触式通信を行う兼用ＩＣチップ1と、第２端子対に接続するように搭載され、第２コイルパターンを利用した非接触式通信を行う非接触通信用ＩＣチップ2と、を有し、第１コイルパターンを利用した非接触式通信と第２コイルパターンを利用した非接触式通信は、同じ通信周波数帯で独立して行われ、第１コイルパターンおよび第２コイルパターンの一方は、他方の内側に形成されているＩＣカード。【選択図】図１
