Abstract

A light source apparatus includes a first light-emitting element to generate an illumination light with a first light emission intensity to be applied to a subject, and a second light-emitting element to generate an illumination light with a second light emission intensity, including at least light with a wavelength different from the illumination light generated from the first light-emitting element. The first light-emitting element and second light-emitting element are arranged, so that the peaks of the first emission intensity and second emission intensity become identical.
