Abstract
A wavelength conversion member which is a resin-molded article made of at least one type of thermoplastic resin selected from polyolefins, polystyrene, styrene copolymers, fluorocarbon resins, acrylic resins, nylons, polyester resins, polycarbonate resins, vinyl chloride resins, and polyether resins. The thermoplastic resin contains less than or equal to 30 mass % of a complex fluoride fluorophore represented by A(MMn)F(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 D, which is the median diameter at a cumulative volume of 50% in particle size distribution, of from 2 μm to 200 μm inclusive. The complex fluoride fluorophore being dispersed in the thermoplasticresin.
