摘要:
A main pole has a front end face including a first end face portion and a second end face portion. A plasmon generator has a near-field light generating surface. A surrounding layer has a first surrounding layer end face and a second surrounding layer end face located on opposite sides of the first end face portion in the track width direction. A gap film has a first gap film end face and a second gap film end face located on opposite sides of the near-field light generating surface in the track width direction. Each of the first and second gap film end faces includes a portion located between the first and second surrounding layer end faces, but does not include any portion interposed between the first surrounding layer end face and the first end face portion or between the second surrounding layer end face and the first end face portion.
