ABSTRACT:
In order to provide a near field light head capable of guiding light efficiently to a near field light generating element, capable of being fabricated easily and at low cost and in correspondence with small-sized formation and thin-sized formation, the near field light head of the present invention has a transparent board including a near field light generating element at a lower face thereof. An upper face or the interior of the transparent board is formed with a lens to be opposed to the near field light generating element. The upper face of the transparent board is mounted with a single mode fiber. The single mode fiber is successively connected with a graded index (GI) fiber and a coreless fiber. An end face of the coreless fiber which is not connected to the GI fiber constitutes a reflecting face disposed at 45 degrees relative to the upper face of the transparent board. The reflecting face is arranged right above the lens.
