Summary:A laser light source module (100) includes: a plate-shaped stem (1); a power supply lead pin (2A, 2B) having an upper end protruding from an upper surface being one of main surfaces of the stem (1) and a lower end penetrating to extend toward a lower surface side, the lower surface being the other of the main surface of the stem (1); a block (3) fixed to the upper surface of the stem (1); a submount substrate (4) that is fixed to a surface of the block (3) and includes the semiconductor laser array (5) mounted thereon, the surface being parallel to the upper surface of the stem (1); the semiconductor laser array (5) located on the submount substrate (4) such that a light emitting direction is parallel to the upper surface of the stem (1); and a collimator lens array (6) that is located on a front surface of the semiconductor laser array (5) and converts an output light beam of the semiconductor laser array (5) into a parallel light beam. The collimator lens array (6) is fixed to the surface of the block (3), the surface being vertical to the upper surface of the stem (1).
