description There is provided a collimator lens capable of adjusting a reflection angle of fluorescence with high accuracy and emitting the fluorescence with high efficiency. Provided is a collimator lens including an aperture, a reflecting portion, and a condensing portion, in which the reflecting portion formed on an inner peripheral surface reflects, to the condensing portion, light emitted from the condensing portion, and the light collected at the condensing portion is emitted toward the aperture or the reflecting portion. Furthermore, there is provided a light source device including the collimator lens, an excitation optical system, and a phosphor.
