Abstract
An optical member includes: a main body having transparency or heat dissipation properties; an optical film disposed on an upper face of the main body; a metal film disposed on the upper face of the main body in a region other than a region where the optical film is disposed; a surrounding part joined via the metal film; and a wavelength conversion part surrounded by the surrounding part. The wavelength conversion part is positioned inward of a periphery of the optical film in a top view. The wavelength conversion part is not directly bonded to the optical film and the main body.
