PROBLEM TO BE SOLVED: To provide an automatic analysis apparatus and a temperature management method of a liquid sample for speedily making the temperature of the liquid sample into a target temperature without separately disposing a preheating means of the liquid sample when a reaction tub for keeping the liquid sample at the target temperature is used. SOLUTION: The automatic analysis apparatus having the reaction tub and the temperature management method of the liquid sample are provided. The automatic analysis apparatus 1 includes: a stirring device 20 for stirring the liquid sample with sound wave issued by a surface acoustic wave element 24 attached to each reaction vessel 5; and a stirring control section for controlling the driving condition of the surface acoustic wave element. In stirring the liquid sample, the stirring control section controls the driving condition of the surface acoustic wave element so that insufficient heat quantity calculated from the difference between the target temperature of the reaction tub 4 and the temperature of the liquid sample, the amount of the liquid sample, and specific heat is equal to the heat quantity of temperature increase of the liquid sample by absorption of sound wave.
