Abstract
A light-source device includes: two long-wavelength light sources that emit red long-wavelength light beams (LWLs); a broadband light source that emits a green broadband light beam (BL); and a multiplexing portion that multiplexes a wavelength region greater than a first predetermined wavelength λof one of the LWLs having a longer peak wavelength and a wavelength region equal to or less than λof the other LWL having a shorter peak wavelength, and that multiplexes a wavelength region greater than a second predetermined wavelength λof the other LWL and a wavelength region equal to or less than λof the BL, wherein intensities of the LWLs at λare equal to or greater than 10% of the peak intensities thereof and intensities of the other LWL and the BL at λare equal to or greater than 10% of the peak intensities thereof.
