第１項に記載の脈波検出装置。[Claims for Utility Model Registration] (1) A device for detecting pulse waves generated from an artery in the human body when pressed against the surface of the human body, with an opening facing the surface of the human body. a container to be placed; and a container provided at the opening of the container to form an airtight pressure chamber within the container, and pressed against the body surface of the human body according to the pressure of the gas filled in the pressure chamber. By this, an elastically deformable diaphragm vibrates with the pressure vibration of the pulse wave, and a pressure fluctuation in the pressure chamber due to a change in the volume of the pressure chamber due to the vibration of the diaphragm is detected. A pulse wave detection device characterized by having a pressure sensor. (2) The diaphragm includes an elastically deformable diaphragm provided in the opening, and is fixedly installed on substantially the entire surface of the diaphragm to restrict elastic deformation of the diaphragm, so that the diaphragm is configured to respond to the pressure vibration. 2. The pulse wave detection device according to claim 1, which is a device comprising a highly rigid plate member that vibrates the diaphragm as a whole.
