PROBLEM TO BE SOLVED: To provide a projector by which the availability of light is enhanced, fixing work is performed by reduced labor and time by easily adjusting an optical axis with a polarization converting element and a lens array and also the structure of the fixing part of a supporting body is simplified. SOLUTION: This projector is provided with a light source, a luminous flux splitting element to split a light beam emitted from the light source into plural partial luminous fluxes, the polarization converting element to convert a luminous flux emitted by the luminous flux splitting element into a specified linear polarized luminous flux and the lens array 416 to transmit the plural partial luminous fluxes emitted from the polarization converting element to the side of an optically modulating device, and the polarization converting element and the lens array 416 are integrated by a holding frame 80 and are fixed at the fixing part 82 of the supporting body 47. Thus, the polarization converting element and the lens array may be attached to the fixing part of the supporting body while adjusting in an integrated state when they are attached at the fixing part, so that the labor and the time of positional adjustment are reduced. |
