Title: IC CARD
Abstract:
An IC card (10A) comprises an insulating substrate (1), on which are formed a mica capacitor (5) including a mica film (6) and electrodes (7a, 7b) on respective sides of the mica film, an antenna coil (2), and an IC chip (3). A terminal for the electrode (7b) of the mica capacitor (5) is formed on the other side, and the terminal is connected with a terminal for the electrode (7a) on the same side using anisotropic conductive adhesive (4) on the insulating substrate (1). The IC card can be manufactured at low cost while having a stable resonance frequency and improved antenna characteristics.
