摘要：
A thin-film magnetic head is constructed such that a main magnetic pole layer, a write shield layer, a gap layer, and a thin-film coil are laminated on a substrate. The thin-film magnetic head has a shield magnetic layer. The shield magnetic layer is connected to the main magnetic pole layer. The shield magnetic layer has a lower front shield part. A front end angle representing an angle formed between a front end face of the lower front shield part and a lower end face is set at an obtuse angle. The front end face is disposed in the medium-opposing surface. The lower end face is disposed at a position closest to the substrate in the lower front shield part.
