Abstract
According to one embodiment, a power source unit includes a substrate and a reflective body. The substrate includes a plurality of light-emitting elements mounted thereon. The reflective body includes a plurality of incident openings each corresponding to one of the plurality of light-emitting elements, an output opening to which light that has passed through the incident opening is output, and a plurality of reflective surfaces that expand from the incident opening toward the output opening. Reflective surfaces included in the plurality of reflective surfaces and positioned on an outermost side are provided to be adjacent to one another, and an angle is set so as to prevent reflective light of light emitted from the light-emitting elements from traveling toward an outer side in a reflective surface formed on the outer side.
