Stage: PROBLEM TO BE SOLVED: To provide a light source device that can more effectively prevent misalignment of the optical axis of a semiconductor laser element with respect to an optical member due to heat generated by driving the semiconductor laser element in the light source device.SOLUTION: The light source device includes a substrate, at least one semiconductor laser element arranged on the substrate, and at least one lens arranged on the light-emitting side of the semiconductor laser element. The substrate has a flat portion for placing the semiconductor laser element and at least two protrusions arranged on both sides of the semiconductor laser element and on the light-emitting side of the semiconductor laser element. The lens is fixed to the protrusions at least in two places by means of a first bonding material.SELECTED DRAWING: Figure 1A (Grant)
