In a dispensing mechanism or a reaction container in which a plurality of contamination factors are assumed, carryover is avoided and analysis performance is maintained. An automatic analysis apparatus includes: an automatic analysis unit 100 which includes a dispensing mechanism including a probe which is configured to dispense a sample or a reagent into a reaction container, and a cleaning mechanism configured to sufficiently clean the probe, and the like; and a control unit 124. The control unit includes a storage unit 124a configured to store count values which indicate weightings to contamination and are set in advance in accordance with a plurality of analysis conditions, a processing unit 124b configured to obtain a cumulative count for each dispensing of the sample or the reagent on the basis of the stored count values and to determine whether the obtained cumulative count exceeds a threshold value set in advance, and an instruction unit 124c configured to instruct an operation of the cleaning mechanism to clean the probe when a result of determination is that the cumulative count exceeds the threshold value.
