Abstract: A method for manufacturing a light emitting device includes: preparing a baseplate having a plate surface on which a protrusion is disposed; forming a first resin frame having an opening on the plate surface, wherein the opening is located above the protrusion; forming a second resin in the opening; detaching the baseplate; bonding a light emitting element to a surface of the second resin surface that has been exposed as a result of detaching the baseplate; and forming a third resin that surrounds lateral faces of the light emitting element and that covers and contacts a portion of the first resin frame.

Abstract: A light emitting device includes a light emitting element having an upper face and lateral faces; a light transmissive member covering at least a portion of the upper face of the light emitting element and transmitting light emitted from the light emitting element; a first reflector covering at least a portion of lateral faces of the light transmissive member; and a second reflector covering the lateral faces of the light emitting element. The first reflector includes a first bottom face and a second bottom face. A plane in which the first bottom face of the first reflector extends is different than a plane in which a lower face of the light transmissive member extends. The second bottom face of the first reflector is located inward of the first bottom face of the first reflector, and is coplanar with the lower face of the light transmissive member. The first bottom face of the first reflector is covered by and in contact with the second reflector.
