Patent ID: 6879258

Claim:
An IC card, comprising: a mica capacitor comprising a mica film acting as a dielectric of said mica capacitor, electrodes formed on both sides of said mica film, an antenna coil, and an IC chip; wherein: said mica film acts as a substrate on which said antenna coil and said IC chip are provided, and stablizes a resonant frequency of said IC card as a result of a low water absorption rate of said mica film; a first capacitor terminal is connected to a first terminal of said IC chip and is linked to a first terminal of said antenna coil; a second capacitor terminal is connected to a second terminal of said IC chip; and a third capacitor terminal is connected to a second terminal of said antenna coil; and said IC chip is mounted on said mica film inside of said antenna coil, such that said IC chip does not overlay said antenna coil.
