Abstract: An optical member includes a conversion member including a first surface that serves as a light-irradiated surface or a light extraction surface, and adapted to convert laser light, which is an excitation light, into light having a wavelength different from a wavelength of the excitation light; a holding member holding the conversion member and including a second surface that is continuous with the first surface of the conversion member; and a wiring having an elongated shape and extending continuously along the first surface of the conversion member and the second surface of the holding member.

Abstract: A light emitting device includes a laser light, a wavelength conversion member, a base member and a lid. The wavelength conversion member includes a plurality of projected portions each extending along a first direction on an upper surface side thereof and arranged side by side in a second direction. Each of the plurality of projected portions has a first surface extending along the first direction. The first surface is inclined with respect to a reference surface. The laser light source and the wavelength conversion member are arranged so that an optical axis of first light from the laser light source extends along the second direction when viewed from above and is inclined with respect to the reference surface, and light directly incident to the first surface along a direction parallel to the optical axis of the first light is regularly reflected toward an upward direction.
