出装置。[Claims for Utility Model Registration] (1) A device for detecting pulse waves generated from blood vessels in the human body when pressed against the surface of the human body, the device comprising: a device for detecting pulse waves generated from blood vessels in the human body in a direction intersecting the blood vessels on the surface of the human body; a plurality of pressure sensors arranged in the body surface, each outputting a pulse wave signal corresponding to a pulse wave generated from the blood vessel when pressed against the body surface; and a pressing means for pressing the pressure sensor against the body surface; Pressing force adjustment that adjusts the pressing force by the pressing means so that the amplitude of the pulse wave signal output from a group of pressure sensors located directly above the blood vessel among the plurality of pressure sensors is approximately constant. A pulse wave detection device comprising: means. (2) The pressing force adjusting means determines the maximum value of the amplitude of the pulse wave signals output from each of the plurality of pressure sensors, and generates a pulse wave signal having an amplitude exceeding a reference value calculated based on the maximum value. The pulse wave detection device according to claim 1, wherein the pressing force is adjusted such that the number of pressure sensors is equal to or greater than a predetermined constant number corresponding to the group of pressure sensors.
