SOLUTION: A polarization converting element 25A is equipped with polarization converting elements 25U and 25D having the longitudinal direction along the Z direction and a polarization converting element 25M having the longitudinal direction along the X direction and disposed between the devices 25U and 25D, and the images of the light emitting part of the light source are included in a stripe effective incident region (hatched region). Only the center part of the lens array may be made larger in the lens size than lenses in other region and the width of an incident face of the polarization converting element may be made half of the width of the corresponding lens. Or, the direction of arc gap of a lamp may be only tilted from an optical axis of a parabolic mirror. When the parabolic mirror with both sides cut is used, the longitudinal direction of the stripe effective incident region of the polarization converting element is made parallel to the longitudinal direction of the aperture end of the parabolic mirror. When a combination of a spherical mirror and a convex lens is used instead of the parabolic mirror, a protruding part of the light source is arranged perpendicular to the optical axis.
