Abstract
A laser attachment device of the present invention is formed of a LD package and a LD holder housing it. A first inner wall of the LD holder to come into contact with a side surface of the LD package is an inclined surface. This allows the facing direction of the LD package to be corrected by the first inner wall being the inclined surface, even when a laser beam emitted from a light emitting chip housed in the LD holder is inclined with respect to an optical axis. Thus, the traveling direction of the laser beam is corrected to the optical axis side.
