IC card.

摘要

An IC card comprises a circuit board (1) on which a plurality of electronic elements (B1 - B4) are mounted and which is sealed inside of a frame (5) and external panels. The electronic elements are arranged to have an empty space with predetermined intervals between the individual elements. A pre-manufactured means (9) of a designated shape is mounted in said empty space between the circuit board (1) and an external panel to provide a reliable and inexpensive way of filling space between the circuit board and the external panel and to protect the electronic elements on the circuit board against forces applied to the IC card. The problem of an insufficient resin filling as it occurs with the prior art is thus avoided.
