An illuminating device has a solid light-emitting element module and a phosphor module joined to the solid light-emitting element module. The solid light-emitting element module has a plurality of the solid light-emitting elements. The phosphor module has a plurality of phosphor-containing parts corresponding to the individual solid light-emitting elements. Thus, a light-emitting part is provided, which has more than one kind of luminescence sources having the solid light-emitting element and the phosphor-containing part. An illumination intensity of a composite light is 150 lux or more at a distance of 30 cm perpendicularly from the light-emitting surface of the light-emitting part.
