Patent ID: 8767352

Claim:
A suspension board with circuit comprising a conductive pattern, comprising: a slider arranged on a surface side of the suspension board with circuit and mounted with a magnetic head, the magnetic head being electrically connected with the conductive pattern; and a light emitting device arranged on the back surface side of the suspension board with circuit and electrically connected with the conductive pattern, wherein the slider comprises an optical waveguide, and an opening extending through the suspension board with circuit in the thickness direction is formed so that a light emitted from the light emitting device passes through and enters the optical waveguide, the conductive pattern comprises: a first terminal provided on a surface of the suspension board with circuit and electrically connected with the magnetic head; a first wire electrically connected to the first terminal, the first wire being formed on the surface of the suspension board with circuit; a second terminal provided on the back surface of the suspension board with circuit and electrically connected with the light emitting device; and a second wire electrically connected to the second terminal, the second wire comprising, a front-side wire formed on the surface of the suspension board with circuit, and a conductive portion allowing the front-side wire and the second terminal to conduct in the thickness direction of the suspension board with circuit at a position different from that of the opening.
