Abstract
A plasmon generator has an outer surface including a plasmon exciting part that faces an evanescent light generating surface of a waveguide. The outer surface further includes first and second inclined surfaces that increase in distance from each other with increasing distance from the plasmon exciting part, and a front end face. The front end face has first and second portions that are connected to each other into a V-shape. The first portion includes a first side lying at an end of the first inclined surface. The second portion includes a second side lying at an end of the second inclined surface. An angle formed between a lower part of the first side and a lower part of the second side is smaller than that formed between an upper part of the first side and an upper part of the second side.
