PROBLEM TO BE SOLVED: To provide a colorimetry device hardly affected by luminous energy irregularity of reflection light from a measurement object region, and having high detection accuracy. SOLUTION: This colorimetry device is provided with: a light emitting means; and a light reception means comprising N(N≥2) kinds of pixels having different spectral sensitivities, and using a line type light receiving element composed by arranging a plurality of the N kinds of pixels in a line. The colorimetry device is so structured that, when it is assumed that the sequence of the 1st kind, the 2nd kind, the 3rd kind and the 4th kind is an ascending order, and the sequence of the 4th kind, the 3rd kind, the 2nd kind and the 1st kind is a descending order, the pixels in the line type light receiving element is arranged according to a rule of a sequence of the ascending order, the descending order, the descending order and the ascending order, or a rule wherein a sequence of the ascending order, the descending order, the descending order and the ascending order is used as a unit and repeated.
