PROBLEM TO BE SOLVED: To provide an analysis device capable of reducing a measurement error caused by a change of a light quantity distribution of a light source. SOLUTION: In a device capable of acquiring concentration information, by acquiring light from a specimen 7 immobilized in a test piece 1 through an optical system constituted of a lens 3, a diaphragm 4, or the like, by an imaging element 5; a wide-band light source 11 for illuminating the test piece 1 is combined with an optical filter 12 for optionally selecting a wavelength of the light acquired by the imaging element 5, to thereby reduce the measurement errors caused by the change of the light quantity distribution of the light source 11.
