A pulse wave detection device comprising a sensor and detecting a pulse wave generated from the artery based on a pulse wave signal output from the pressure sensing element, wherein the pulse wave detected by each of the plurality of pressure sensing elements is amplitude determining means for sequentially determining the amplitude of a wave; and calculating an amplitude difference between the amplitude of the pulse wave detected by the plurality of pressure-sensitive elements and the amplitude of the pulse wave detected a predetermined time ago for each pressure-sensitive element. an amplitude difference calculation means that calculates an amplitude difference, and an amplitude difference calculated by the amplitude difference calculation means,
When a predetermined number or more of all pressure-sensitive elements are all positive or all negative, it is determined that there is no body movement in the living body. A pulse wave detection device comprising: body movement determining means for determining that a body movement has occurred.
