Abstract:
Provided is a wavelength conversion member that can reduce strain under stress occurring at the interface between a substrate and a phosphor layer and is therefore less susceptible to breakage during use. The wavelength conversion member  1  comprises a substrate  10  and a phosphor layer  20  bonded on the substrate  10 , the phosphor layer  20  including inorganic phosphor powder  22  dispersed in a glass matrix  21 . In a temperature range of 30° C. to a setting point of the phosphor layer  20 , a relation −10×10 −7 ≤(α 1 −α 2 )≤10×10 −7  (/° C.) is satisfied where α 1  represents a coefficient of thermal expansion of the substrate  10  and α 2  represents a coefficient of thermal expansion of the phosphor layer  20 . The setting point is defined by Tf−(Tf−Tg)/3 (where Tg represents a glass transition point and Tf represents a deformation point).

Claim (Index 6):
The wavelength conversion member according to  claim 1 , wherein the inorganic phosphor powder is made of one or more selected from the group consisting of nitride phosphor powder, oxynitride phosphor powder, oxide phosphor powder, sulfide phosphor powder, oxysulfide phosphor powder, halide phosphor powder, and aluminate phosphor powder.
