Abstract:
A light-emitting device includes a light-emitting element, a light-transmissive member having an upper surface in a rectangular shape and a lower surface to be bonded to the light-emitting element, and a covering member disposed to cover lateral surfaces of the light-transmissive member and lateral surfaces of the light-emitting element such that the upper surface of the light-transmissive member is exposed. The light-transmissive member includes a main portion that constitutes the upper surface in the rectangular shape and a peripheral portion that is positioned around the main portion and has a smaller thickness than the main portion. In lateral surfaces of the peripheral portion, recesses are formed each of which is positioned at a location of a corresponding one of corners of the rectangular shape, and is depressed toward the main portion.
