Abstract: A method of manufacturing a light-emitting device includes flip-chip mounting a plurality of light-emitting elements on a substrate separately from each other. A light-transmissive member is bonded on the plurality of light-emitting elements. The light-transmissive member includes a matrix and a manganese-activated fluoride fluorescent material that functions as a wavelength conversion member. A lateral surface of the light-transmissive member is exposed between at least one pair of the plurality of light-emitting elements that are adjacent with each other. A light-reflective covering member is provided on the substrate to cover the lateral surface and a top surface of the light-transmissive member. A portion of the light-reflective covering member that is located on a top surface of the light-reflective covering member is removed to expose the light-transmissive member. The substrate and the light-reflective covering member are cut to yield individual pieces of light-emitting devices.

Abstract: A light emitting module includes: a light guide member including: an emission region defined by a sectioning groove, a light source placement part located in the emission region, and a light adjusting hole that, in a schematic top view, is located between the sectioning groove and the light source placement part; and a light source disposed in the light source placement part. A refractive index of an inside of the light adjusting hole is lower than a refractive index of the light guide member. In the schematic top view, the light adjusting hole is positioned to intersect with a first straight line connecting a center of the light source and a farthest point in the sectioning groove, the farthest point being farthest from the center of the light source.
