Patent ID: 8493426

Claim:
A light source device, comprising: a semiconductor laser; a coupling lens that converts laser light from the semiconductor laser to a light flux, the coupling lens having an optical axis; a sheet-metal member that holds the semiconductor laser and the coupling lens, the sheet-metal member including a first bent portion and a second bent portion; a photopolymerizable resin cured to fix the coupling lens on the sheet-metal member; and a main body; wherein the sheet-metal member includes: a first portion extending in a first direction perpendicular to the optical axis and holding the semiconductor laser; a second portion that extends in a second direction perpendicular to the first direction and is fixed to the main body; and a third portion holding the coupling lens, the third portion extending in a third direction that is parallel to the second direction and being disposed at a location different from a location of the second portion in the first direction; wherein the first portion and the second portion are connected via the first bent portion, wherein the second portion and the third portion are connected via the second bent portion.
