A thermal assisted magnetic recording head that performs magnetic recording while locally heating a magnetic recording medium includes: a plasmon generator that generates a surface plasmon and that generates near-field light from the surface plasmon on a front end surface positioned on an air bearing surface opposing the magnetic recording medium; a dielectric body layer positioned around the plasmon generator; and an adhesion layer positioned between the plasmon generator and the dielectric body layer. The adhesion layer is made from at least one of IrOx, RuOx, NiOx and CoOx.
