Abstract
A near-field light generating element has a core that guides a laser light in a direction of a disk while reflecting the laser light, and a cladding that encapsulates the core in an inner portion, and lengths of a longitudinal direction and a transverse direction of an incident side end surface of the laser light in the core are formed so as to match the lengths of a long axis direction and a short axis direction of the laser light that is entered to the core.
