An electronic sphygmomanometer includes a pressure control unit configured to conduct pressurization control on a cuff (pressure control toward a specific direction) and acquire a cuff pressure signal at a time of the pressurization control to thereby measure a pressure pulse wave a displacement decision unit configured to decide whether displacement has occurred between a position of the cuff and a virtual position of the heart based on an output from an angle sensor when the pressurization control is being conducted and a return processing unit configured to, when it is decided that displacement has occurred, stop the pressurization control and conduct depressurization control on the cuff to thereby return an intra-cuff pressure to a specific pressure value that denotes a pressure value before the occurrence of the displacement. The pressure control unit resumes the pressurization control after processing by the return processing unit.
