Abstract

PURPOSE: To improve the reliability, by forming a substrate through hole closed by a conductor which is used as a bonding terminal connected with an electronic part, on a rear face side of a contact terminal, and making the thickness of the conductor of the contact terminal, thicker than that of the conductor of the other conductor part by a specific range. CONSTITUTION: A through hole 13 and a cavity hole 14 are formed on a substrate body 11, and a copper foil is laminated thereon. Then a necessary wiring pattern is formed through a process for forming and etching a resist. Then a contact terminal is projected on a wiring pattern located on the contact terminal 12 by a plating method under a condition that it is thicker than a conductor 15 of the other wiring pattern by 20-300 micron m. Then the electronic parts such as IC chips 16 or the like, are loaded on a printed wiring board 10 for an IC card, the printed wiring board is placed on a fitting part 110 formed on the IC card 100, and a plastic film 120 is laminated on the surface. Whereby the surface of the IC card and the surface of the contact terminal are aligned on the same plane, and the accumulation of the dust, water or the like thereon can be prevented.
