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 8):
The wavelength conversion member according to  claim 1 , having a wheel shape.
