Abstract
A semiconductor laser device includes a submount having a bottom plate part and a projecting part projecting from a surface of the bottom plate part, and a semiconductor laser bonded to the submount. The semiconductor laser includes a semiconductor substrate, a semiconductor structure part that is formed on the semiconductor substrate and has an active layer, a first electrode, and a second electrode. A side face of the semiconductor laser facing the projecting part, and the second electrode thereof are respectively bonded to the projecting part facing the semiconductor laser and the bottom plate part with a bonding member. The bonding member for bonding the projecting part and the side face of the semiconductor laser is such that an end part thereof in a z-direction in which the projecting part projects is located further away in the z-direction than a surface of the semiconductor substrate of the semiconductor laser.
