The plasmon generator has a near-field light generating surface. The medium facing surface includes a first region including neither of the exit end face and the near-field light generating surface, and a second region including the exit end face and the near-field light generating surface. The protective film includes a first portion covering the first region, and a second portion covering the second region.
