A light emitting element includes an LED element that emits an excitation light having a single peak wavelength within a range of greater than or equal to 380 nm and less than or equal to 500 nm; a fluorescent body to which at least a portion of the excitation light enters to emit fluorescence; and a light extraction surface that emits an output light formed by superimposing the excitation light and the fluorescence. The output light exhibits light emission over a range of at least greater than or equal to the peak wavelength of the excitation light and less than or equal to 1050 nm, and all of the output light have a light emission intensity of greater than or equal to a light emission intensity at 1050 nm within a range of at least the peak wavelength of the excitation light to 1050 nm.
