Thin IC card

摘要

A thin IC card includes a circuit board on which functional parts are mounted and a through-hole defining an edge of a battery lodging section in which a battery is disposed, the circuit board being embedded in a molding-resin section with the reverse surface of the board exposed. The battery lodging section is aligned with the through-hole of the circuit board. Electrical connections between the circuit board and the battery are effected in a recess or cutouts in the circuit board. The battery is embedded in the lodging section using an expandable resin to make the card surface flat.
