PROBLEM TO BE SOLVED: To provide an autoanalyzer in which a dispensing probe can be cleaned in a short time and with good efficiency and which is provided with a probe cleaning mechanism whose running costs can be made low. SOLUTION: By using a dispensing probe 26, a sample and a reagent which are sucked into the probe are dispensed into a reaction container. In addition, a high-temperature heating device 41 is installed at least in a part at the dispensing probe 26, near the dispensing probe 26 and a piping flow passage which communicates with the dispensing probe 26. When the dispensing probe 26 is to be cleaned, a cleaning liquid inside the dispensing probe 26 or a cleaning liquid inside the piping flow passage communicating with the dispensing probe 26 is heated by the high-temperature heating device 41 so as to be boiled instantaneously. The cleaning liquid and the sample or the reagent which remain are discharged from the tip of the dispensing probe 26 by a high pressure which is generated due to a change in a volume which swells suddenly, by a vapor and by air bubbles. |
