摘要： A near field light generating element has a polyhedron core and a clad covering the core so as to contact side surfaces of the core. The polyhedron core has a reflection surface that reflects a luminous flux in a direction different from a direction of introduction of the luminous flux via one end side of the near field light generating element. A luminous flux condensing unit condenses the luminous flux reflected by the reflection surface and propagates the condensed luminous flux to the another end side. A near field light generation unit generates near field light from the propagated condensed luminous flux and emits the near field light to the exterior of the near field light generating element via the another end side. The near field light generation unit has an end surface that is exposed to the exterior on the another end side and has at least one side surface that is shielded by a light-shielding film.
