Abstract
A disclosed semiconductor laser module includes a semiconductor laser device; a waveguide optical function device that has an incidence end on which laser light emitted from the semiconductor laser device is incident and that guides the incident light; and a protrusion that is provided on an extension line of a light path of the laser light emitted from the semiconductor laser device, the extension line extending beyond the incidence end.
