Abstract: A light source apparatus includes a first light source section that outputs blue light along a first illumination optical axis,the second light source section are arranged side by side and outputs excitation light along a second illumination optical axis substantially parallel to the first illumination optical axis, a reflection member that reflects the excitation light in such a way that the reflected excitation light travels along a third illumination optical axis that intersects the first illumination optical axis and the second illumination optical axis, a wavelength converter on which reflects converted light having a wavelength different from a wavelength of the excitation light, and a light combiner that is located in the position where the first illumination optical axis and the third illumination optical axis intersect each other and transmits the blue light and the excitation light but reflects the converted light.
