A light-emitting device includes a light-emitting element having an upper surface serving as a light-extracting surface, a first light-transmissive member bonded to the upper surface of the light-emitting element and including an inorganic material as a main component and a wavelength conversion member, and a second light-transmissive member bonded to an upper surface of the first light-transmissive member and including an inorganic material as a main component. A periphery of a lower surface of the first light-transmissive member is located outward of a periphery of the upper surface of the light-emitting element in a plan view. A periphery of an upper surface of the second light-transmissive member is located inward of a periphery of the upper surface of the first light-transmissive member in the plan view.
