Abstract

An IC card having a circuit board provided with wiring formed on at least one of two surfaces of the circuit board, a terminal base fixed to one surface of a front portion of the circuit board and having a multiplicity of electrode terminals disposed on its upper surface, a plurality of electronic parts mounted on the two surfaces of the circuit board, and a package in which the circuit board on which the electronic parts are mounted is incorporated while exposing the electrode terminals to the outside of the package.

Claims

1. An IC card comprising:

a circuit board having two opposed surfaces and electrical wiring disposed on at least one of said surfaces, said circuit board including an exposed edge along which electrode terminals for connection of said circuit board to an external device are disposed;

a plurality of electronic parts mounted on said surfaces;

a package including a frame enclosing part of said circuit board, first and second covers disposed on said frame to enclose said circuit board while leaving said electrode terminals exposed, said frame including an internal portion on which said circuit board is mounted intermediate of said first and second covers; and

a terminal base mounted on one of said surfaces, said electrode terminals being disposed on said terminal base spaced from said circuit board for positioning said electrode terminals relative to said first cover.

2. An IC card according to claim 1 wherein said circuit board is bonded to said frame.

3. An IC card according to claim 1 wherein said terminal base includes through holes through which said electrode terminals are electrically connected to said electrical wiring disposed on said circuit board.

4. An IC card according to claim 1, wherein said circuit board includes through holes for electrically connecting said electronic parts mounted on said surfaces of said circuit board.

5. An IC card according to claim 4 wherein said terminal base includes through holes through which said electrode terminals are electrically connected to said electrical wiring disposed on said circuit board.
