Abstract: A wave-length conversion inorganic member can includes a base body and an inorganic particle layer on the base body. The inorganic particle layer can include particles of an inorganic wave-length conversion substance which is configured to absorb light of a first wave-length and to emit light of a second wave-length different from the first wave-length. The inorganic particle layer can include an agglomerate of a plurality of the particles. Each of the plurality of the particles are in contact with at least one of the other particles or the base body. A cover layer comprises an inorganic material, and the cover layer continuously covers a surface of the base body and surfaces of the particles. The inorganic particle layer has an interstice enclosed by the particles, or by the particles and one of the base body and the cover layer.
