Zusammenfassung:A phosphor device (100) comprises a substrate (110), a phosphor layer (120) that includes a plurality of pores (121), a reflecting layer (130) that is provided between the substrate (110) and the phosphor layer (120), a joining layer (140) that includes a first metal and is provided between the substrate (110) and the reflecting layer (130), and a metal layer (150) that includes a second metal having a higher melting point than the first metal and is provided between the reflecting layer (130) and the joining layer (140). The reflecting layer (130) has a multilayer structure in which a high-refractive-index layer (131) and a low-refractive-index layer (132) having a lower refractive index than the high-refractive-index layer (131) are alternately layered.
