Abstract

A method for producing an optical wavelength conversion member () composed of a sintered body containing, as main components, AlOand a component represented by formula ABO:Ce; an optical wavelength conversion member; an optical wavelength conversion component including the optical wavelength conversion member; and a light-emitting device including the optical wavelength conversion member or the optical wavelength conversion component. The production method of the sintered body includes firing in a firing atmosphere having a pressure of 10Pa or more and an oxygen concentration of 0.8 vol. % or more and less than 25 vol. %.
