description A thin film magnetic head includes: an element part formed by laminating an antiferromagnetic layer, a fixed magnetic layer, an insulating barrier layer, and a free magnetic layer on a substrate; and a protective layer that protects an end surface of the element part opposite a recording medium. The insulating barrier layer is formed using an AlOx film or an MgO film. An adhesive layer is provided between the protective layer and the end surface of the element part on which the insulating barrier layer is exposed, a nitride existing on at least an interface between the adhesive layer and the insulating barrier layer
