Automatic analyzer

An automatic analyzer that analyzes a sample, the automatic analyzer comprising:

• an incubator which holds a reaction container in which a liquid mixture of the sample and a reagent is accommodated;
• a sample dispensing unit including a dispensing tip, which dispenses the sample by aspirating the sample from a sample container in which the sample is accommodated, stores the aspirated sample in a storage portion of the dispensing tip and then discharges the sample to the reaction container;
• and
• a measurement portion which measures the amount of sample in the storage portion on the basis of a detected signal obtained by detecting light passing through the storage portion while irradiating the storage portion with light, wherein
• the measurement portion is caused to measure the amount of sample in the storage portion again after discharging the sample to the reaction container when the amount of sample measured by the measurement portion is less than a threshold amount, and
• the measurement portion is disposed on the incubator.
