A light emitting device includes a base body forming a recess defined by a bottom surface and a side wall thereof, a conductive member whose upper surface being exposed in the recess and whose lower surface forming an outer surface, a protruding portion disposed in the recess, a light emitting element mounted in the recess and electrically connected to the conductive member, and a sealing member disposed in the recess to cover the light emitting element. The base body has a bottom portion and a side wall portion integrally formed of a resin, an inner surface of the side wall portion is the side wall defining the recess and has a curved portion, and the protruding portion is disposed in close vicinity to the curved surface. With this arrangement, a thin and small-sized light emitting device excellent in light extraction efficiency and reliability can be obtained.
