An electronic sphygmomanometer includes a cuff to be attached to a blood pressure measurement site, a pump and a valve for adjusting a pressure to apply on the cuff, a pressure sensor for detecting the pressure of the cuff, a central processing unit (CPU) for calculating a blood pressure value from the cuff pressure, a memory for recording the blood pressure value, and an operation unit for performing a blood pressure measurement. Further, the CPU acquires information on an application voltage of the valve or the pump at a time of blood pressure measurement, and the information on the application voltage is stored in the memory. The CPU corrects the application voltage so that control of the valve or the pump is carried out based on the application voltage stored in the memory.
