A dummy pole piece is selectively formed on a write gap layer. After that, a thin film coil of a first layer is formed on the write gap layer and, simultaneously, a coil connecting part integral with the thin film coil is formed on at least the side wall surfaces of the dummy pole piece. Then an insulating layer is formed so as to cover the thin film coil, the dummy pole piece and the coil connecting part, and the write gap layer and the insulating layer is polished until a top pole piece, a top connection piece, and the dummy pole piece are exposed. Subsequently, a thin film coil of a second layer is formed on the write gap layer and a coil connecting part integral with the thin film coil is formed on the exposed face of the coil connecting part.
