摘要： A thin-film magnetic head includes a slider substrate and a write element. The slider substrate has an air bearing surface at one side thereof. The write element has a recording magnetic pole film. The recording magnetic pole film is disposed on a plane crossing the air bearing surface over the slider substrate and has a large-width portion and a small-width portion continuously arranged in the named order toward the air bearing surface. The small-width portion has a smaller width than the large-width portion. Of the large-width portion and the small-width portion, at least the small-width portion has a first portion and a second portion. The second portion is continuous with an upper end of the first portion and has both side faces inclined in such a direction as to increase the width. An external angle of the first portion formed by a plane parallel to a bottom face and the side face is larger than an external angle of the second portion formed by a plane parallel to the bottom face and the side face.
