Abstract:
A phosphor wheel has a phosphor-supporting surface on which is formed a phosphor that generates fluorescent light in response to the incidence of light; and a reflecting surface that reflects the incident light, the phosphor-supporting surface and the reflecting surface being formed both to be parallel to each other to have a distance between them in the perpendicular direction of each surface.
