A head suspension includes a load beam to apply load onto a head that writes and reads information to and from the hard disk and a flexure attached to the load beam and supporting the head. The flexure has write wires and read wires connected to the head. The flexure includes a substrate made of a conductive thin plate, a base insulating layer made of flexible resin and formed on the substrate, and the wires are arranged on the base insulating film. A ground layer is formed at least partly between the substrate and the base insulating layer. The ground layer only corresponds to the write wires in a width direction of the flexure. The conductivity of the ground layer is higher than that of the substrate that is made of a conductive thin plate.
