A multi-wavelength light source device includes three light source devices. The light source device includes a plurality of light emitting elements, and a dispersing section making wavelengths of light beams emitted from the respective light emitting elements different from each other, a spectral line width of the emitted light beam in each of the light source devices is equal to or greater than 0.2 nm, a wavelength of the red light beam in the light source device for emitting the red light beam is greater than 612 nm, a wavelength of the green light beam in the light source device for emitting the green light beam is greater than 525 nm and smaller than 538 nm, and a wavelength of the blue light beam in the light source device for emitting the blue light beam is greater than 465 nm and smaller than 468 nm.
