Light emitting device

A light emitting device comprising:

• a base substrate forming a package that includes a positive lead electrode, a negative lead electrode, and a molded body holding the positive and negative lead electrodes, the base substrate having a recessed portion at a flat upper surface thereof, the recessed portion having an inner wall and a bottom surface, the inner wall being inclined such that a diameter of the recessed portion increases in an upward direction from the bottom surface;
• a light emitting element bonded to the bottom surface of the recessed portion;
• and
• a sealing member provided in the recessed portion that does not cover the flat upper surface of the base substrate,
• wherein the sealing member contains surface-treated particles, or particles coexisting with a dispersing agent, the particles having a particle diameter of 1 nm or more and 100 μm or less, the particles being made of an inorganic material, the inorganic material being free of a phosphor,
• at least a part of an edge portion of the sealing member is a region located in the vicinity of an edge of the recessed portion which is a boundary between a surface of the inner wall and the flat upper surface of the base substrate, at least one of the particles and aggregates of particles being unevenly distributed in the region, and
• the at least one of the particles and aggregates of particles are more localized in a surface region of the sealing member in the vicinity of the edge of the recessed portion as compared to the surface region of the sealing member in a central portion of the recessed portion.
