Abstract
A head suspension provided with a plate welding structure relaxes a laser beam positioning accuracy, improves a mass production ability, suppresses the generation of spattered matter, and prevents the deformation of plates during welding. The head suspension () has a base plate () to be attached to a carriage and a load beam () having a rigid part () and a resilient part (). The load beam is supported by the base plate and applies load on a slider that is arranged at a front end of the load beam. A reinforcing plate () is laid over the base plate, and a laser beam is emitted to a weld spot to weld the reinforcing plate and base plate together. The reinforcing plate is provided with thin parts () each containing the weld spot. Each thin part is irradiated with a laser beam to weld the base plate and reinforcing plate together.
