Abstract: A light emitting device includes: a base having an upper face; a light emitting element mounted on the upper face of the base; one or more bonding members disposed on the upper face of the base outward of the light emitting element; a light transmissive member bonded to a portion of the upper face of the base by the one or more bonding members; and a protective film that continuously covers the light emitting element, the upper face of the base, lateral faces of the one or more bonding members, and a lower face of the light transmissive member. A gap is located between the upper face of the base and the lower face of the light transmissive member and configured to allow a space in which the light emitting element is mounted to communicate with an outside of the light emitting device, wherein the gap is defined by the upper face of the base, the lower face of the light transmissive member, and the one or more bonding members.
