Abstract: A high-sensitive contactless chromaticity measuring device according to the present invention, includes: a lens unit to receive light emitted from a measurement object; a light distribution unit including an optical fiber to receive the light passing through the lens unit and distribute the received light through n paths to output the light to the other side, wherein a numerical aperture is greater than a predetermined reference value, a condensing lens to reduce an incidence angle of the light output to the other side of the optical fiber to a target angle or more, and n color filters to transmit different wavelengths of the light passing through the condensing lens; and a signal conversion unit including a photodiode to convert the light transmitted from the light distribution unit into an electrical signal.
