摘要： PROBLEM TO BE SOLVED: To provide a wavelength conversion member where some of the light emitted from light source is transmitted through and some of the light is subjected to wavelength conversion, the wavelength conversion member which can reduce color unevenness caused by the difference in luminous intensity distribution of transmitted light and wavelength-converted light and can give uniform color in a lighting surface, and to provide a light-emitting device using the same, and a method of manufacturing the wavelength conversion member.SOLUTION: The wavelength conversion member contains (A) a garnet phase and (B) one or more phases selected from a perovskite phase, a monochromic phase and a silicate phase, and is formed by sintering ceramics of a polycrystal where a fine crystal consisting of the phase (B) is contained and dispersed into the phase (A). The light transmitted through the wavelength conversion member is scattered on the interface between the garnet phase and the perovskite phase, monochromic phase or silicate phase in the wavelength conversion member. Therefore, the light-emitting device using the wavelength conversion member has a smaller loss of light and great uniformity of emission color. More specifically, the light-emitting device using such wavelength conversion member has improved evenness in the distribution of light between the light transmitted through the wavelength conversion member and the light whose wavelength has been converted, compared to the conventional products, making it possible to obtain a better lighting surface with reduced unevenness in color.
