Projector and method for manufacturing projector

A projector comprising:

• a spatial light modulator provided for each color light flux and configured to modulate the light flux in accordance with an image signal;
• a light combining system configured to combine the color light fluxes outputted from the spatial light modulators;
• a projection system configured to project the light combined by the light combining system;
• a fixing member configured to integrally fixes the spatial light modulator and the light combining system;
• a base on which the spatial light modulator and the light combining system fixed to the fixing member are mounted and to which the projection system is fixed;
• and
• a cover member configured to covers the spatial light modulators and the light combining system mounted on the base,
• wherein the base and the cover member form a cooling duct through which cooling air for sequentially cooling the spatial light modulator for the respective color light flux flows.
