ABSTRACT:
A first pole tip 212 at a write element 2 is provided projecting above a first yoke 211. A second pole tip 222 is adhered onto a gap film 23 that is adhered onto the first pole tip 212. The front end portion of a second yoke 221 is laminated on the second pole tip 222. At least either the first pole tip 212 or the second pole tip 222 is constituted of a material having a higher saturation magnetic flux density than that of permalloy. At least either the first yoke 211 or the second yoke 221 is constituted of a material having a higher resistivity than that of permalloy.
