摘要：
A near-field light generating element has an outer surface. The outer surface includes a bottom surface, first and second inclined surfaces, an edge part that connects the first and second inclined surfaces to each other, and a front end face located in a medium facing surface. The front end face includes a first side that lies at an end of the first inclined surface, a second side that lies at an end of the second inclined surface, and a tip that is formed by contact of the first and second sides with each other and forms a near-field light generating part. Each of the first side and the second side has a lower part and an upper part that are continuous with each other. An angle formed between the upper part of the first side and the upper part of the second side is smaller than that formed between the lower part of the first side and the lower part of the second side.
