Abstract
A light source-unit which is used for a thermally assisted magnetic head, comprises a laser diode and a sub-mount which the laser diode is joined. The sub-mount comprises a joint-surface which the laser diode is joined and a convex part protruding from the joint-surface. The light source-unit comprises an alloy layer, made of alloy, which is formed between the surface of the convex part and an opposing-surface, of the laser diode, opposing to the joint-surface.
