<P>PROBLEM TO BE SOLVED: To provide a fluorescent body wheel, a light source device, and a projector that can inhibit reduction of light use efficiency as a whole system including the fluorescent body wheel. <P>SOLUTION: A wavelength conversion element includes a wheel substrate 31 as a substrate, a light emitting element 40 including a fluorescent body layer 41 provided on the substrate and including a fluorescent body 100 and a light transmission layer 42 provided opposite to the substrate of the fluorescent body layer 41, and a first reflection part 43a provided on a first lateral surface 34a of the light emitting element 40 crossing an interface between the fluorescent body layer 41 and the light transmission layer 42, which first reflection part 43a reflects a light advancing parallel to the substrate in an inside of the fluorescent body layer 41 in a direction opposite to the substrate. <P>COPYRIGHT: (C)2012,JPO&INPIT |
