Provides a semiconductor laser device, as well as a manufacturing method therefor, capable of solving a problem of yield decreases in a structure for mounting a nitride semiconductor laser element onto a mount member. The nitride semiconductor laser device has a submount 2, and a nitride semiconductor laser element 1 which is mounted on a surface of the submount 2 with a solder 4 so that a nitride semiconductor is exposed from a side face thereof. The solder 4 is positioned between the submount 2 and the nitride semiconductor laser element 1 and has a width W3 smaller than a lateral width W4 of the nitride semiconductor laser element 1.
