A light irradiation angle is set with respect to a first surface so as to detect only either first reflected light or second reflected light. Then, light is emitted from a light irradiation part at the set irradiation angle while a detection chip is kept in motion, either the first reflected light or the second reflected light is detected by a reflected light detection part, and positional information of the detection chip is acquired on the basis of the result of the detection of the first or second reflected light. The detection chip is moved, on the basis of the acquired positional information, to a detection position where detection of a substance to be detected is performed. While the detection chip is kept at the detection position, detection of the substance to be detected is performed through detection of sample light.
