脈波検出装置。[Claims for Utility Model Registration] A pulse wave sensor that is pressed against the surface of a human body and detects pulse waves generated from blood vessels in the human body can be moved along the body surface in a direction intersecting the blood vessels. A pulse wave detection device comprising a support device supporting the pulse wave in the cross direction, and detecting the pulse wave by moving the pulse wave sensor to a position suitable for detecting the pulse wave in the cross direction. The structure includes a plurality of flexible plates spaced apart from each other in the direction, perpendicular to the intersecting direction, and parallel to each other, and parallel to the body surface of the plurality of plates. By fixing one end of each direction in a fixed position and disposing the pulse wave sensor at the other end, the pulse wave sensor is immovable in a direction perpendicular to the body surface and cannot be moved in the cross direction. A pulse wave detection device characterized in that the device is supported so as to be movable.
