PROBLEM TO BE SOLVED: To provide a wavelength conversion member capable of suppressing reduction in light-emitting intensity or melting of a constituting material over time when high power LED or LD light is irradiated and a light-emitting device including the same.SOLUTION: The wavelength conversion member includes a laminate containing a phosphor layer formed by dispersing phosphor powders and a heat conductive filler in an inorganic binder, and a translucent heat dissipation layer, formed on at least one principal plane of the phosphor layer, having heat conductivity higher than that of the inorganic binder.SELECTED DRAWING: Figure 1 |
