PROBLEM TO BE SOLVED: To provide a compact automatic analysis apparatus. SOLUTION: A mirror 27 is installed behind a photometry cell 4 for accommodating each kind of solution to be analyzed, thus enabling luminous flux 30 for measurement to pass a reaction liquid 40 for two times and at the same time enabling the luminous flux to pass a step section 4A that is formed at the upper section of the photometry cell. As a result, the thickness of the photometry cell 4 can be thinned for making compact the apparatus. At the same time, a passage length of fixed luminous flux can be always maintained without being affected by the difference of the amount of the reaction liquid and the chattering of a liquid surface, thus achieving an accurate analysis.
