- forming a circuit, electronic parts, and an I/O portion on at least one of said first and second surfaces of said circuit board; and filling said frame with synthetic resin in a mold passing through said opening to said first and second surfaces of said circuit board to hermetically seal said circuit, electronic parts, and I/O portion with a thickness no greater than the thickness of said frame;
- 2. A method of manufacturing an IC card comprising:
- injecting a synthetic resin into a mold so that a frame is formed, said frame integrally comprising a periphery having a thickness corresponding to the thickness of said IC card and a circuit board supporting portion disposed intermediate the thickness of said periphery within said frame;
- forming a circuit, electronic parts, and an I/O portion on at least one of opposed first and second surfaces of said circuit board and an opening which penetrates from the first surface to the second surface; and
