Abstract

A light-emitting device includes: a base member that includes conductor wirings; a light-emitting element that is mounted on the base member and emits first light; a wavelength conversion member that is disposed on or above an upper surface of the light-emitting element and is adapted to absorb at least part of the first light and emit second light with a wavelength longer than a wavelength of the first light; a light-reflective film that is disposed on an upper surface of the wavelength conversion member; and an encapsulating member that covers the light-emitting element, the wavelength conversion member, and the light-reflective film. A ratio (H/W) of a height (H) to a width (W) of the encapsulating member is smaller than 0.5.
