The invention provides a projector capable of improving the efficiency of cooling a cooling target. The projector (1) includes: a plurality of light modulation devices (351R, 351G, 351B) configured to modulate a plurality of color lights; and a cooling device (4) configured to cool the light modulation devices (351R, 351G, 351B), wherein the cooling device includes a cooling fan (5), and a duct (6) configured to guide air received from the cooling fan (5) toward the plural light modulation devices(351R, 351G, 351B), and the duct (6) including a first duct portion (7A) configured to allow the air to flow through the two light modulation devices (351G, 351B) from sides of the two light modulation, and a second duct portion (7B) which communicates with the first duct portion (7A) and guides a part of the air flowing through the first duct portion (7A) toward the other light modulation device (351R).
