摘要：
A magnetic head includes a main magnetic pole, a shield having an end face located in a medium facing surface to wrap around an end face of the main magnetic pole, and a gap part provided between the main magnetic pole and the shield. The shield includes a bottom shield, two side shields, and a top shield. The gap part includes first and second gap layers. In a manufacturing method of the magnetic head, a mold is formed on the top surface of the bottom shield, the mold having a shape determined by photolithography and being intended to be removed later. Next, the two side shields are formed on the top surface of the bottom shield by performing plating without forming a seed layer. Next, the mold is removed and then the first gap layer, the main magnetic pole, the second gap layer, and the top shield are formed in succession.
