摘要：
A method of manufacturing a magnetic head includes the step of forming an accommodation part and the step of forming a return path section. The return path section lies between a main pole and a top surface of a substrate, and connects a shield and part of the main pole away from a medium facing surface to each other so that a space through which part of a coil passes is defined. The accommodation part accommodates at least part of the return path section. The step of forming the return path section forms first to third portions simultaneously. The first portion is located closer to the top surface of the substrate than is the space. The second portion is located closer to the medium facing surface than is the space. The third portion is located farther from the medium facing surface than is the space.
