LSI3は、基板1にフリップチップ方式で実装されるインレットとされている。 LSI3 is the inlet implemented by a flip chip method on a substrate 1. アンテナパタン4は例えば、厚さ0.3mmのアルミニューム箔をエッチングして形成される。 Antenna pattern 4 may, for example, be formed by etching the aluminum foil having a thickness of 0.3 mm.

カード基板1にはコンデンサ電極6,7が設けられ、これらコンデンサ電極6,7は、誘電体であるPET製のカード基板1をアルミニュームパターンで挟むことにより静電容量を持ち、この実施の形態では、電極面積4mm×10mmで、約10PFの容量となっている。 Capacitor electrodes 6 and 7 is provided on the card substrate 1, these capacitor electrodes 6 and 7, the card substrate 1 made of PET is a dielectric having a capacitance by sandwiching with aluminum pattern, this embodiment so in an electrode area 4 mm × 10 mm, and has a capacity of about 10 pF.

上記LSI3は、図3に示すようにコンデンサ電極6,7を介してアンテナパタン4に電気的に接続されている。 The LSI3 is electrically connected to the antenna pattern 4 via the capacitor electrodes 6 and 7 as shown in FIG.

カード基板1、LSI3及びアンテナパタン4、さらに、コンデンサ電極6,7は、被覆材としての表面シート10と裏面シート11とにより被覆されている。 Card substrate 1, LSI 3 and the antenna pattern 4, further, the capacitor electrodes 6 are covered with the topsheet 10 and the backsheet 11 as coating material. 表面シート10と裏面シート11としては、厚さ0.075mmのPETシートが用いられる。 The topsheet 10 and backsheet 11, PET sheet with a thickness of 0.075mm is used. 表面シート10と裏面シート11との間には絶縁性の充填材12が充填されている。 Filler 12 of insulation is filled between the topsheet 10 and the backsheet 11. 表、裏面のシート10,11と充填材12とは真空ホットプレスにより一体化されたのち、カード状に打ち抜かれてカード化される。 Table, after being integrated by vacuum hot pressing the back surface of the sheet 10, 11 and the filler 12, is carded by punching into card shape.
