PROBLEM TO BE SOLVED: To provide an automatic analyzer with a liquid dispenser capable of precisely dispensing, independently of a physical property, such as, the viscosity of a sample in a dispenser to dispense a predetermined quantity of biological sample, including blood and urine. SOLUTION: The automatic analyzer includes a nozzle for sucking a sample; a pressure resource for sucking or discharging a sample generating a pressure in the nozzle; a tube for connecting the nozzle and the pressure resource; a pressure measuring means for measuring the pressure in the tube; a memory storing means for storing pressure change during dispensing; and an arithmetic means for comparing pressure change stored in the memory storing means or calculate it, in which a discharge quantity is controlled, by calculating with the arithmetic means from a pressure change during suction operation.
