The phosphor region includes a phosphor that is disposed on at least a part of a circumference of a circle with a first radius from a rotation center of the substrate. The substrate includes a ventilation region and a heat conduction region. The ventilation region includes a plurality of openings that is located closer to the rotation center of the substrate than the phosphor region. The heat conduction region is located farther away from the rotation center of the substrate than the phosphor region.
