Abstract:
A fluorescent member includes: a plurality of fluorescent particles; an inorganic binder; and a plurality of pores. An upper surface of the fluorescent member is a light extraction surface of the fluorescent member. The plurality of pores are localized in a vicinity of at least one of the plurality of fluorescent particles in a cross section that is parallel to the upper surface of the fluorescent member and extends through the fluorescent particles and the pores.
