Abstract
A light-emitting module () includes a substrate (), a plurality of light-emitting elements () formed on the substrate (), and phosphor layers () covering each of the light-emitting elements (). Each of the phosphor layers () includes a first phosphor region () and a second phosphor region () that are divided in the direction substantially parallel to the surface of the substrate (). Each of the first phosphor region () and the second phosphor region () includes a phosphor that absorbs light emitted from the light-emitting element () and emits fluorescence. The maximum peak wavelength of fluorescence emitted from the first phosphor region () is longer than that of fluorescence emitted from the second phosphor region ().
