A solar simulator in which locational unevenness of irradiance is reduced by using a small and simple optical system, having an array of light emitters 2 with a plurality of point light emitters planarly arranged in a given range 24, an effective irradiated region 4 spaced apart from a surface having the point light emitters 26 arranged thereon, and a reflection mirror 6 disposed to surround the given range 24 of the array. Preferably, a distance L between the point light emitter positioned at the outermost portion of given range 24 of the array of light emitters 2 and a light-reflecting surface of the reflection mirror is half of a pitch a of the array of the point light emitters and, more preferably, the distance L is larger than half of a width b of each point light emitter, and smaller than half of the pitch a. |
