A suspension substrate according to the present invention includes: an insulating layer; a spring material layer provided on one face of the insulating layer and having conductivity; and a plurality of wirings provided on the other face of the insulating layer. One wiring includes a head-side wiring part extending from the head portion, and a plurality of division wiring parts respectively bifurcated from the head-side wiring part. The spring material layer includes a spring material main body, and a wiring spring material part separated from the spring material main body, via a groove. A conductive connecting part extending through the insulating layer is provided in the insulating layer. Each of the division wiring parts of the one wiring is connected with the wiring spring material part, via the conductive connecting part.
