Claim Text:
1. A color measurement device comprising: a light source for irradiating a color measurement object with light; a spectral unit for dispersing the light reflected from the color measurement object; and a light detection unit including multiple pixels, the light detection unit generating an electric signal corresponding to the intensity of the light dispersed by the spectral unit, wherein the light source includes a light-emitting diode having a peak value of emission intensity in a near-ultraviolet region whose range is not less than 380 nm and not more than 420 nm, and a plural types of fluorescent members each having a peak value of fluorescence intensity in a wavelength zone that is not less than 420 nm, and not more than 730 nm, wherein the light source has a luminescence spectrum of which the lowest intensity in a wavelength zone that is equal to or more than 400 nm, or equal to or less than 700 nm is 20% or more of the maximum intensity.
