PROBLEM TO BE SOLVED: To provide a light source device that can control the temperature of a semiconductor laser efficiently and quickly, and a projection device.SOLUTION: A light source 21 emits a light flux and is held by a light source case 26 which includes a first salient 264 (second salient 265). A Peltier element 53 is thermally connected to a part of the light source case 26, and adjusts temperature of the light source 21 via the light source case 26. A light condensing optical system 22 is arranged in a travelling direction of the light flux from the light source 21. A holder 23 holding the light condensing optical system 22 includes a first recess 232 corresponding to the first salient 264 of the light source case 26, and engages the first salient 264 with the first recess 232.
