PROBLEM TO BE SOLVED: To provide a light source unit capable of concentrating light from a plurality of light emitting points to the same light concentration point while increasing intensity of the light at the light concentration point without enlarging a device.SOLUTION: A light source unit comprises: a light source 32 including a plurality of LED light emitting elements 33a, 33b; and a reflective member 35A facing the light source 32, and reflecting and concentrating the light of the light source 32. A reflective surface 37 of the reflective member 35A has curvature such that each optical axis of radiation light of each of the LED light emitting elements 33a, 33b included in the light source 32 disposed at the focal position corresponding to the reflective surface 37 performs the light concentration to the same light concentration point F of an irradiation surface D. |
