Abstract
Provided is a fluorescent wheel for a projector capable of suppressing the heating of the phosphor layer and a light emitting device for a projector using the same. The fluorescent wheel for a projector includes: a phosphor layer (); an annular ceramic substrate () which includes a first principal surface provided with the phosphor layer () and a second principal surface located on an opposite side to the first principal surface and has a higher thermal conductivity than the phosphor layer (); and a reflective layer () provided on the second principal surface of the ceramic substrate ().
