Abstract:
A method of manufacturing a wavelength conversion member includes: preparing a composite by layering a layered body and a ceramic sheet that includes a phosphor, the layered body including a pair of light-reflective green sheets each containing a reflective material, and a light-shielding green sheet containing a light shielding material with the light-shielding green sheet being layered between the pair of reflective green sheets; and pressurizing and firing the composite.
