Wavelength conversion member and light-emitting device

Disclosed is a wavelength conversion member which is a resin-molded article made of at least one or more than two types of thermoplastic resin(s) selected from the group consisting of polyolefins, polystyrene, styrene copolymers, fluorocarbon resins, acrylic resins, nylons, polyester resins, polycarbonate resins, vinyl chloride resins, and polyether resins, the thermoplastic resin(s) containing less than or equal to 30 mass% of a complex fluoride fluorophore represented by A2(M1-xMnx)F6 (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) and having a particle diameter D50, which is the median diameter at a cumulative volume of 50% in particle size distribution, of from 2 [mu]m to 200 [mu]m inclusive, the complex fluoride fluorophore being dispersed in the thermoplastic resin(s).
