Abstract
A light-emitting device () includes a substrate (); a wiring pattern (), an electrode land (), a sealing resin layer (), a wire (), and a resin dam () that are disposed on the substrate (); at least one light-emitting element () that emits light having a peak emission wavelength in a wavelength range of 430 to 480 nm; a green phosphor () that is excited by primary light emitted from the light-emitting element () to emit light having a peak emission wavelength in a green region; and a first red phosphor () that is excited by the primary light to emit light having a peak emission wavelength in a red region. The first red phosphor () emits no light in a wavelength range of 700 nm or more and absorbs no light in a wavelength range of 550 to 600 nm.
