Abstract: A light emitting device includes a base member, a light emitting element, a wire, a protective film, first and second resin members, and a light shielding portion. The base member has a conductive member. The wire connects the light emitting element and the conductive member. The protective film covers the conductive member to be spaced apart from a portion of a connecting portion. The first resin member has a first gas barrier property with respect to hydrogen sulfide and a first light resistance. The second resin member has a second gas barrier property with respect to hydrogen sulfide lower than the first gas barrier property and a second light resistance higher than the first light resistance. The light shielding portion is disposed on a surface of the base member and disposed on a line connecting the light emitting element and the first resin member.
