    摘要: A plasmon-generator of the invention is configured to include a first configuration member including a near-field light generating end surface; and a second configuration member joined and integrated with the first configuration member and not including the near-field light generating end surface. The first configuration member is configured to contain Au as a primary component and to contain any one or more elements selected from a group of Co, Fe, Sb, Nb, Zr, Ti, Hf, and Ta, and is configured so that a content percentage X1 of the contained element is within a range between 0.2 at % or more and 2.0 at % or less. Thereby, thermostability, optical characteristic, and the process stability are satisfied. Also, heat dissipation and heat generation suppression effect are extremely superior.
