The purpose of the present invention is to constantly keep a state in a flow cell steady by filling a detection flow channel with a liquid. The configuration of the present invention for solving the aforementioned problem is as follows. Specifically, the present invention is an automatic analysis apparatus provided with a detection unit including a flow cell that accommodates a liquid serving as an analysis subject; a suction nozzle that is positioned upstream of the flow cell and that sucks the liquid to be introduced into the flow cell; a pump that is positioned downstream of the flow cell and that supplies the liquid to the flow cell; flow channels that connect the flow cell, the suction nozzle, and the pump; a power source; and a power-cutting instructing unit that gives an instruction to cut the power supply at least to the pump. The automatic analysis apparatus is characterized by being provided with a control unit that performs first liquid supply processing when the power-cutting instruction from the power-cutting instructing unit is not received, and that performs second liquid supplying processing when the power-cutting instruction from the power-cutting instructing unit is received, thus supplying the liquid to the flow cell.
