摘要：
A convex-portion forming layer is formed between a current-confinement aperture and a multilayer mirror, and forms a convex portion on each boundary between layers forming the multilayer mirror. The convex portion includes a plane equal to or larger than a spot size of the laser light, where the spot size is decided by a diameter of the current-confinement aperture, a predetermined diffraction angle of the laser light due to the current-confinement aperture, and a distance from the current-confinement aperture.
