1. An automatic analyzer, comprising:
a flow cell detector;
a nozzle that is connected to the flow cell detector by a flow path and aspirates or discharges liquid;
a reservoir that is provided with a table and a table driving mechanism that rotates the table or moves the table up and down; and
a cleaning tank that is disposed on the table, wherein
a position of the nozzle is fixed, and a cleaning water discharge port that discharges cleaning water used for cleaning the nozzle is fixed such that the cleaning water can be discharged at an angle φ with respect to a plane perpendicular to a central axis of the nozzle, and
an upper part of a side wall of the cleaning tank is continuous with an upper discharge unit at a side facing a discharge outlet provided in the reservoir and a spatula-shaped part that projects outward the cleaning tank at a side facing the upper discharge unit.
