PURPOSE: To provide a simple step at low cost and improve reliability in connection, by using a manufacturing step, in which a plug pin of a male-type connector is formed from a thick part of a metallic lead frame with the thick part and a thin part and a conductive circuit with a land is formed from the thin part, and molding these members in a body with resin. CONSTITUTION: A metallic rolled sheet 5, in which a thick part 6 and a thin part 7 are rolled in a body, is manufactured to form a lead frame. The lead frame is bent to form a plug pin 3 of a connector. After the bending step, the plug pin 3 and the land 4 are subjected to surface treatment of plating to reduce electric resistance in connection. The lead frame after the bending and surface treatment is mounted in a mold. The lead frame is molded in a body by injecting a synthetic resin to form an integrated circuit board with a connector. |
