PROBLEM TO BE SOLVED: To prevent exfoliation of a near-field light generating element, and to suppress a drop in use efficiency of light propagating via a waveguide resulting from an adhesion layer, in a near-field light generating device having the near-field light generating element disposed above the waveguide with a buffer layer and the adhesion layer interposed therebetween.SOLUTION: The near-field light generating device 15 includes the waveguide 31; the buffer layer 33 disposed on the top surface 31c of the waveguide 31; the adhesion layer 38 that is formed by incompletely oxidizing a metal layer and disposed on the buffer layer 33; and the near-field light generating element 32 disposed on the adhesion layer 38. The adhesion layer 38 has a resistance-area product which is higher than that of the metal layer unoxidized and lower than that of a layer that is formed, by completely oxidizing the metal layer. A layered structure consisting of the buffer layer 33, the adhesion layer 38 and the near-field light generating element 32 has a peel-test adhesive strength higher than that of a layered structure, consisting of the buffer layer 33 and the near-field light-generating element 32. |
