To provide a light source unit (63) which can increase luminance and a projector (10) including this light source unit. This light source unit includes a luminous wheel (71) having a segment area (1) on which a luminescent material layer (131) is formed which emits light of a predetermined wavelength band by receiving light, and a segment area (2) which is made into a transmission portion (141) which transmits light, a primary light source (72) which shines light of a visible wavelength band on to the luminous wheel (71), a secondary light source (82) which emits light of a wavelength band which is different from light from the luminescent material layer (131) and light from the primary light source (72), a collective optical system (151) which collects light from the luminous wheel (71) and the secondary light source (82) to cause them to converge to the same optical path, and a light source control device (41) which controls the emission of light from the light sources (72,82). |
