| description | Provided is a chemical analysis device having a stirring function for stirring a reagent or the like with a specimen to be measured by means of an ultrasonic element, wherein the presence or absence of a reaction solution and the height of the liquid level of the reaction solution can be estimated without using a means such as a sensor or vision. In a chemical analysis device having an ultrasonic stirring mechanism, the ultrasonic stirring mechanism is provided with: a piezoelectric element; a plurality of electrodes disposed in the piezoelectric element; a power supply unit that applies a voltage to the electrode; a detection unit that measures the electrical impedance for each of the plurality of electrodes or for any combination of electrodes; and an analysis unit that determines the liquid level in the reaction container on the basis of the electrical impedance detected by the detection unit that measures the electrical impedance in a state in which the reaction container into which two or more different |
