Abstract

A radiation thermometer has a broadband light source which generates broadband light; an optical filter which, when the broadband light is incident on the measuring target object, passes only light in a predetermined wavelength range of reflected light and heat radiation light from a measuring target object; a light receiver which receives the light in the predetermined wavelength range through the optical filter; and a calculator which calculates a temperature of the measuring target object by using reflected light intensity and heat radiation intensity of the light in the predetermined wavelength range received by the light receiver, wherein an emission spectrum of the broadband light is a spectrum with a full width at half maximum which is equal to or wider than the predetermined wavelength range, and with light intensity increasing while a wavelength thereof becomes longer in the predetermined wavelength range.
