A method for manufacturing a magnetic head, includes forming, on a non-magnetic film, a main magnetic pole film with a body portion and a write magnetic pole portion continuous with the body portion, and etching the non-magnetic film such that an undercut is formed around the body portion and beneath the write magnetic pole portion. The undercut penetrates beneath the write magnetic pole portion in a track width direction. The method includes wet etching the non-magnetic film beneath the main magnetic pole film at the undercut, the undercut being at least partially filled with an organic filler. The method also includes, after removal of the organic filler, covering at least both sides of the write magnetic pole portion with a magnetic gap film, and forming a write shield film adjacent to the magnetic gap film. The undercut forms a hollow in the non-magnetic film underlying the write magnetic pole portion.
