Disclosed is a wavelength conversion member which is a resin-molded article having dispersed therein a complex fluoride fluorophore that absorbs light with a blue wavelength component and emits light including a red wavelength component and that is represented by A 2 (M 1-x Mn x )F 6 (in the formula: M is at least one type of tetravalent element selected from Si, Ti, Zr, Hf, Ge, and Sn; A is at least one type of alkali metal selected from Li, Na, K, Rb, and Cs and including at least Na and/or K; and x is from 0.001 to 0.3), wherein the hue of the wavelength conversion member when light is not emitted is as follows in CIELAB (CIE 1976): L* = from 40 to 60 inclusive; a* = from 0 to +1 inclusive; and b* = from +2 to +15 inclusive. |
