Abstract:
A method for producing a suspension board with circuit includes the steps of (7) removing a first electroless plating layer corresponding to a first terminal and/or a second electroless plating layer corresponding to a second terminal by etching, (8) removing a metal supporting board in contact with the lower surface of a first conductive layer filling the inside of a first opening portion, and (9) providing an electrolytic plating layer on the surface of the first terminal with the first electroless plating layer removed and/or the surface of the second terminal with the second electroless plating layer removed and the lower surface of the first conductive layer exposed from the inside of the first opening portion by electrolytic plating supplying electricity from the metal supporting board.
