ABSTRACT:
A method of producing a circuit board includes the steps of: electroplating a mold surface of a mold so that a circuit body made of a metal plating layer is formed on the mold surface of the mold; pressing the mold against a board made of a thermoplastic resin; heating and retaining the mold so that the circuit body is bonded to the board under heat and pressure; and releasing the mold from the board after cooling the board to thereby transfer the circuit body to the board. The circuit board may be in the shape of box with the circuit body on the inner surfaces thereof.
