Abstract
With a configuration for adhering and fixing a laser diode holder to a holding portion, sufficient supporting strength of the laser diode holder is given without unnecessarily increasing an amount of an adhesive agent and a solidification time of the adhesive agent. The adhesive agent is applied so as to couple an outer circumferential surface of the laser diode holder and a wall surface of an opening provided in a housing. Here, one or both of the outer circumferential surface of the laser diode holder and the wall surface of the opening of the housing has a recess at a portion to which the adhesive agent is applied. The recess has such a shape that an inner side of an outer edge is concaved, and the outer edge at least partially has a shape extending toward a coupling portion between the laser diode holder and the housing.
