A colorimetry device having a light source for irradiating light to a measured object, a cover part provided with a take-out port for taking out light diffused from the measured object, and a placing part on which the measured object is placed, the measured object being put between the cover part and the placing part, so as to effect the color measurement of the measured object. A hinge mechanism is provided, so that when the measured object is placed on the placing part and the cover part is in a closed state, a measurement space dividing section for defining a measurement space between the cover part and the placing part is provided. A measuring light may also be arranged to irradiate the rear face of the measured object.
