PROBLEM TO BE SOLVED: To provide an automatic analyzer which can increase the efficiency of stirring for mixing a reagent and a sample in a reaction container and can reduce the amount of the reagent and the sample which can be stirred to an extremely small level.SOLUTION: The automatic analyzer includes: a reaction container 102 which can contain a dispensed sample and a reagent; an array-like ultrasonic generation unit 201 arranged on the side of the reaction container 102; and an acoustic lens 206 between the ultrasonic generation unit 201 and the reaction container 102, the acoustic lens causing the ultrasound waves emitted from the ultrasonic generation unit 201 to collect in a desired position of the mixture of the sample and the reagent in the reaction container 102, the acoustic lens 206 changing the focus point 209 of the ultrasound waves emitted from the ultrasonic generation unit 201 in the reaction container 102.SELECTED DRAWING: Figure 2 【課題】反応容器内の試薬とサンプルの混合における攪拌効率の向上、及び、攪拌可能な試薬とサンプルを微量化し得る自動分析装置を提供する。【解決手段】自動分析装置は、分注されたサンプルと試薬を収容し得る反応容器１０２、反応容器１０２の側方に配されるアレイ状の超音波発生部２０１、及び、超音波発生部２０１と反応容器１０２との間に配され、超音波発生部２０１から出射された超音波を反応容器１０２内のサンプルと試薬の混合物の所望の位置に集束させる音響レンズ２０６を備え、音響レンズ２０６は、反応容器１０２内における超音波発生部２０１から出射された超音波の集束点２０９を変更する。【選択図】図２
