Zusammenfassung:PROBLEM TO BE SOLVED: To provide a wavelength conversion material capable of forming a wavelength conversion member with excellent luminescent color homogeneity and high brightness.SOLUTION: A wavelength conversion material is formed by dispersing inorganic phosphor powder and glass powder in a resin matrix, and an absolute value of the difference in refractive index between the resin matrix and the glass powder is 0.05 to 0.5.
