In a semiconductor laser holder for holding a frame-type semiconductor laser composed of a frame plate formed of metal and having a laser element mounted on the top face thereof and a frame package formed of resin, formed so as to surround the laser element from the front, rear, left, and right sides thereof, and having a light-exit opening formed at the front end thereof to let laser light from the laser element exit therethrough, the semiconductor laser holder has an upper holder member and a lower holder member formed of metal, fitted together from above and below, having housing depressions formed in the fitting faces thereof to house the semiconductor laser, and having an opening at the front end thereof to let the laser light exit therethrough. The lower holder member has depressions formed in the fitting face thereof to accommodate heat-sink projections of the frame plate protruding from the left and right edges of the frame package of the semiconductor laser, and the upper holder member has elevations formed on the fitting face thereof to fit into the depressions so as to hold the heat-sink projections against the floor faces of the depressions.
