Abstract: A wavelength converter is provided with a light-transmitting substrate and with a thin film that is formed on a surface of the light-transmitting substrate and that contains a phosphor. A sintered body that constitutes the light-transmitting substrate has an average particle size of 5-40 μm. The light-transmitting substrate contains at least 10-500 ppm by mass of MgO. The principal component of the phosphor is an α-sialon that is indicated by the general formula (Caα,Euβ) (Si,Al)12(O,N)16 (provided that 1.5
