Provided are: a glass that itself emits white light; and a light-emitting element and light-emitting device that are coated by such a glass. The white light-emitting glass does not contain crystals, emits fluorescent light in the wavelength region of 380-750 nm by means of excitation by light having a wavelength of 240-405 nm, and contains SnOx (where x=1 to 2, and x typically is 1 or 2), P2O5, and MnOy (where y=1 to 2, and y typically is 1 or 2). The light-emitting element and the light-emitting device are formed by coating the primary surface a semiconductor light-emitting element with such a glass.
