Abstract
Provided is a method of producing a wavelength conversion member, comprising the steps of forming a fluorescent material layer on the top surface of a substrate and filling a translucent material into the fluorescent material layer. The fluorescent material layer contains fluorescent material particles and has voids between the fluorescent material particles. The translucent material has a lower refractive index than the fluorescent material particles and is filled into a part of the voids to form a filled region in a manner to allow the voids to be partially left unfilled with the translucent material.
