Abstract:
The invention provides a wavelength conversion member and a light emitting device which each has a reduced proportion of voids and transmits less source light without causing a decrease in light conversion efficiency offered by phosphor particles having a large particle size. A wavelength conversion member  100  is configured to convert light with a specific wavelength to light with other wavelength, and includes a substrate  110  including an inorganic material, and a phosphor layer  120  joined to the substrate  110  and including phosphor particles  122  that absorb light and emit converted light and a translucent ceramic  121  that binds the phosphor particles  122  to one another. The phosphor particles  122  include two kinds of particles each having a designated particle size distribution. The two kinds of particles are larger particles having a larger average particle size and smaller particles having a smaller average particle size wherein the ratio of the average particle size of the larger particles to the average particle size of the smaller particles is 2 to 4. The ratio of the volume of the larger particles to the volume of the smaller particles is not more than 5.7.

Claim (Index 2):
The wavelength conversion member according to  claim 1 , wherein the ratio of the volume of the larger particles to the volume of the smaller particles is not more than  4 .
