A light source apparatus (1) is provided with: a light source unit (10); a light guide body (20), which is disposed at a position where light emitted from the light source unit (10) enters and has a tapered shape with the width thereof gradually increased toward the light outgoing surface from the light incoming surface; and an optical filter (30), which is disposed at a position where the light outputted from the light guide body (20) enters and is configured such that the spectrum of a specific wavelength band is attenuated. Thus, the light source apparatus, which has the irradiation angle controlled and has reduced dimensions, and a simulated solar light irradiation apparatus provided with the light source apparatus are provided. |
