Abstract
An object of the present invention is to provide a light reflective substrate capable of achieving high optical reflectance even though fine particles are not used as a material, and a light emitting device using the same. The light reflective substrate according to the present invention comprises: a glass matrix; and RNb 2 O 6 crystal and/or R 4 Nb 2 O 9 crystal (R is at least one of Mg, Ca, Sr and Ba) in the glass matrix.
