Abstract
A light-emitting device includes: a light-emitting element having a polygonal shape; a wavelength conversion plate; a bonding member; and a first covering member. The bonding member has an inclined surface continuous from a region between a conversion-plate first surface and an element second surface and inclined from a peripheral region of the conversion-plate first surface toward an element first surface at lateral surfaces of the light-emitting element. The inclined surface at a first cross section along a first cross-sectional line, which connects a center of the light-emitting element in a plan view to a vertex of the polygonal shape, is closer to a lateral surface of the light-emitting element than the inclined surface at a second cross section along a second cross-sectional line, which connects the midpoint of a side connecting the vertex and its adjacent vertex of the polygonal shape to the center of the light-emitting element.
