PROBLEM TO BE SOLVED: To provide a reflector in which a mechanical property is excellent, and while a degree of reflection of light of a shorter wavelength band in a visible light region is suppressed, the degree of reflection of light in a region other than the shorter wavelength band is high; and a light emitter module having a light emitter on the reflector.SOLUTION: A reflector comprises a sintered body that includes, when the total components are assumed to be 100 mass%: at least 75 mass% and at most 84 mass% of an Al content by an AlOconversion; at least 10 mass% and at most 14 mass% of a Ba content by a BaO conversion; and at least 3 mass% and at most 13 mass% of Si by a SiOconversion, and has a glass phase that includes: crystals of alumina, barium oxide, and anorthite; and Si in the sintered body. |
