A head suspension includes an arm turned around a spindle, the load beam, and a flexure. The load beam includes a rigid part, a resilient part, and a head. The rigid part has a body and a joint. The joint is connected to a first end of the resilient part that is supported with the arm. The head is for writing and reading data to and from a disk and is positioned at a front end of the load beam to receive load from the load beam. The flexure is attached to the load beam and supports the head. A rail is formed along each side edge of the body of the rigid part and rises in a thickness direction of the body. The first end of the resilient part has extensions that extend over the joint of the rigid part toward the body of the rigid part. The extensions are fixed to the body of the rigid part.
