A diode chip is sealed by a glass material. There are provided a light emitting diode chip and a glass member in close contact with at least one portion of the surface of the light emitting diode chip. The glass member has a surface shape containing a curved surface at least a portion thereof. The curved surface is preferably a portion of a spherical surface or a spheroidal surface. The glass member has a surface shape containing a spherical portion and a flat portion, and the diode chip is preferably disposed on the flat portion.
