Abstract: A fluorescence emitting element includes: a wavelength conversion member that is plate-shaped and includes a fluorescent material, the wavelength conversion member including a first principal surface and a second principal surface that is on an opposite side from the first principal surface; and a metal film bonded to at least one surface out of the first principal surface and the second principal surface. In a plan view of the wavelength conversion member, the wavelength conversion member includes a region that does not overlap the metal film, and the metal film includes a bonding surface that is bonded to the at least one surface, and an exposed surface on an opposite side from the bonding surface.

Abstract: A transmissive fluorescence emitting module includes: a fluorescent substrate that consists essentially of a fluorescent material; a metal member bonded to a principal surface that the fluorescent substrate includes; and a rotator that rotates the fluorescent substrate and the metal member about an axis extending in a thickness direction of the fluorescent substrate. In a plan view of the fluorescent substrate, the fluorescent substrate includes a region that does not overlap the metal member, the region being annular ring-shaped.
