Abstract
A suspension board with circuit includes a circuit board including a metal supporting board, an insulating layer formed on the metal supporting board, a conductive layer formed on the insulating layer, and an optical waveguide disposed on the circuit board. The optical waveguide includes an under clad layer, a core layer formed on the under clad layer, and an over clad layer formed on the core layer and included in the core layer when projected in the thickness direction of the core layer. The optical waveguide is provided with a positioning portion to position the optical waveguide and a near-field light generating unit for generating near-field light by a light emitted from the optical waveguide, and a protective layer to cover the positioning portion.
