Abstract
A light emitting device is a light emitting device for use in a photodynamic therapy. The light emitting device includes: a solid-state light-emitting element that emits primary light in which an energy density is 0.5 W/mmor more; and a wavelength converter including a first phosphor that emits first wavelength-converted light. The first wavelength-converted light has a light component across at least a whole of a wavelength range of 700 nm or more and less than 800 nm. Energy of fluorescence emitted from the wavelength converter is 100 mW or more. A medical device includes the light emitting device.
