A magnetic head suspension of the present invention includes a flexure, a load-bent portion, a load beam and a base portion. The base portion has a main body and an embedded body embedded in the main body so as to be positioned in a region where the main body and the load-bent portion overlap with each other. The main body is made of a material having a specific gravity lower than that of the embedded body. The embedded body is made of a material which can be welded to the load-bent portion. The load-bent portion and the embedded body are welded to each other to thereby join the load-bent portion and the base portion to each other.
