Provided is a wavelength conversion member that can exhibit an antireflection function for incident light and emitted light at various angles and can increase the luminous efficiency. A wavelength conversion member 10 includes: a phosphor layer 1 containing a glass matrix 3 and phosphor particles 4 dispersed in the glass matrix 3; and a low-refractive index layer 2 formed on a surface of the phosphor layer 1 and having a refractive index equal to or smaller than a refractive index of the phosphor particles 4, wherein the low-refractive index layer 2 has an uneven surface structure and a waviness profile formed by the uneven surface structure has a root-mean-square gradient WΔq of 0.1 to 1.
