Abstract: A fluorescent member according to present invention is composed of a sintered body for wavelength conversion containing a matrix containing magnesium oxide and magnesium hydroxide as main components, and phosphor particles dispersed in the matrix. A thermal conductivity of the fluorescent member is preferably 5 W/(m·K) or higher. A fluorescent member having both a satisfactory thermal conductivity and a satisfactory fluorescent property is provided without requiring a high-temperature sintering process (a high-temperature process at a temperature higher than 250° C.). Further, a method for manufacturing such a fluorescent member and a light-emitting apparatus using such a fluorescent member are provided.
