<P>PROBLEM TO BE SOLVED: To provide an illumination apparatus including a plurality of light source sections, which reduces luminance and color unevenness of illuminating light, and exhibits sufficient imaging performance. <P>SOLUTION: The illumination apparatus 10 includes: a first light source section 1; a plurality of second light source sections 2a and 2b; and an optical axis conversion element (square truncated pyramid shaped reflector 3) which emits a light beam incident from the first light source section so that an exiting optical axis of the light beam approximately coincides with an illumination optical axis, and emits light beams incident from the plurality of second light source sections 2a and 2b so that exiting optical axes of the light beams become approximately parallel to the illumination optical axis L in positions close to the illumination optical axis L. <P>COPYRIGHT: (C)2010,JPO&INPIT |
