摘要：
A near field light emitting element has a first film made of e.g. Al, an intermediate film made of e.g. SiN and a second film made of e.g. Al on an emergent surface of a solid immersion lens made of a high-refractive material. A first hole is made in the first film, and a second hole is made in the second film. The second hole is smaller in area than the first hole.
