。[Scope of Claim for Utility Model Registration] A compression device, a pipe that supplies pressure from a pressure source to the compression device, and a pulse sound generated from an artery in the living body when the compression device compresses the living body. In a blood pressure measurement device that is equipped with a pulse sound sensor that detects a pulse sound and measures a blood pressure value based on the generation and disappearance of the pulse sound, in order to detect the pulse sound propagating within the piping from the compression device, A blood pressure measuring device characterized in that a cavity resonator capable of resonating the pulse sound is formed in the pipe, and the pulse sound sensor is provided at a position of an antinode of a standing wave vibration mode generated in the cavity resonator. .
