摘要：
A plasmon generator has a front end face located in a medium facing surface of a magnetic head. The plasmon generator includes a first portion formed of a first metal material and a second portion formed of a second metal material. The first portion has an inclined surface facing toward the front end face. The second portion is located between the inclined surface and the front end face, and includes a first end face located in the front end face and a second end face in contact with the inclined surface. The second metal material is higher in Vickers hardness than the first metal material. The first portion has a plasmon exciting part. The front end face generates near-field light.
