Abstract
A dynamic range is extended while suppressing an increase in a chip area. A biological sample analyzer of the present disclosure includes: a first semiconductor photodetection element that detects first light generated by irradiation of a biological sample and generates a first signal; a second semiconductor photodetection element that detects second light reflected by the first semiconductor photodetection element among the first light and generates a second signal; and a processing circuit that acquires information regarding the first light on the basis of the first signal and the first signal.
