Patent ID: 8593823

Claim:
A suspension board with circuit defining a front face, which faces a medium, and a back face and comprising a conductive pattern, the conductive pattern comprising: a first conductive pattern including a head-side terminal provided on the front face of the suspension board with circuit and electrically connected with a magnetic head; an external terminal electrically connected to the external circuit board; and a signal wire for electrically connecting the head-side terminal to the external terminal, the signal wire being formed only on the front face of the suspension board with circuit, and a second conductive pattern including a device-side terminal provided on the back face of the suspension board with circuit and electrically connected with an electronic device; a supply-side terminal electrically connected to a power supply; and a power supply wire for electrically connecting the device-side terminal to the supply-side terminal, the power supply wire comprising a front-side wire formed on the front face of the suspension board with circuit; and a back-side wire formed on the back face of the suspension board with circuit, wherein the signal wire and the front-side wire are spaced apart from each other, wherein the power supply wire comprises a conductive portion allowing the front-side wire and the back-side wire to conduct each other in the thickness direction of the suspension board with circuit, and wherein the conductive portion comprises: a front-side conductive portion formed continuously with the front-side wire; and a back-side conductive portion formed continuously with the back-side wire, the front-side conductive portion and the back-side conductive portion being electrically connected with each other.
