Abstract: An optical member holding device includes a holding member, an optical member and an elastic member. The holding member has a recess defined by one or more lateral surfaces and a bottom surface with a through-hole opening at the bottom surface. The optical member is disposed on the bottom surface of the recess, and includes a light transmissive part. The optical member has an upper surface and one or more lateral surfaces. The elastic member consists of an inorganic material. The elastic member includes a main part disposed on the upper surface of the optical member, and a plurality of supporting parts each extending outward and bending downward to be in contact with the one or more lateral surfaces of the recess and the one or more lateral surfaces of the optical member to exert elastic force that secures the optical member in a predetermined location in the recess.

Abstract: A light-emitting device includes a substrate; a light-emitting element mounted on the substrate; a first light-transmissive member bonded to an upper surface of the light-emitting element via an adhesive; and a second light-transmissive member placed on an upper surface of the first light-transmissive member. In a plan view of the light-emitting device, a peripheral edge of a lower surface of the first light-transmissive member is positioned more inward than a peripheral edge of the upper surface of the light-emitting element. The adhesive extends from the upper surface of the light-emitting element to a lower surface of the second light-transmissive member, the adhesive covers a side surface of the first light-transmissive member, and the adhesive is separated from the substrate.

Abstract: A light emitting device includes a substrate, a light emitting element mounted on the substrate, a light transmissive member placed on an upper surface of the light emitting element, and a sealing member which seals the light emitting element and the light transmissive member. The light transmissive member is a plate-shaped member not containing a phosphor and is larger than the light emitting element when viewed from above. The sealing member includes a first sealing member which is formed of a light reflecting member for reflecting light emitted from the light emitting element and covers side surfaces of the light emitting element, and a second sealing member which contains a phosphor for converting the light emitted from the light emitting element into light having wavelength different from wavelength of the light emitted from the light emitting element and covers at least an upper surface of the light transmissive member.
