Provided is a light source device in which one or more of at least one type of light-emitting element are mounted, and which is equipped with a fluorescent body excited by output light from the light-emitting elements, wherein, when all of the mounted light-emitting elements prior to mounting of the fluorescent body are caused to emit light, the light source device has an output light peak wavelength in a first wavelength region longer than 440 nm and not longer than 490 nm and an output light peak wavelength in a second wavelength region not shorter than 380 nm and not longer than 440 nm, whereby, when an object to be illuminated (such as clothing) is illuminated with the light, the colors of white, navy blue, and black can be simultaneously made to appear brightly. |
