Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a small-sized color measuring device directed to general users. SOLUTION: The color measuring device (10) comprises a plurality of color sensing elements (11-13), each of which generates an electrical signal that depends on the wavelength and the intensity of light incident thereon and is characterized by a gain function that relates the electrical signal to the wavelength and intensity of light incident on the elements (11-13), in which each of the gain function is different from the others of the gain functions; an optical system (17) for illuminating each of the color-sensing elements (11-13) with a light from a light source; and a data processor (21), that is connected to each of the color-sensing elements (11-13) and determines the intensity and wavelength of a light signal from the electrical signal by a controller.
