Abstract

A light-emitting unit according to the present invention includes: a fluorescent section for emitting light upon irradiation with a laser beam; and a wavelength selection filter being provided so as to face the fluorescent section. The wavelength selection filter reflects the laser beam toward the fluorescent section and transmits fluorescence emitted from the fluorescent section.
