Provided is a pulse wave detection device with which it is possible to improve pulse wave detection accuracy by flexibly varying the state of contact between the pressure detection element used in contact with a site on the human body, and the site on the human body. Also provided is a biometric information measurement device comprising same. The biometric information measurement device 200 is equipped with: a sensor unit 6 having a row of elements 60 comprising a plurality of pressure detection elements arranged in a direction B and a pressing surface 6b comprising a row of elements 70 arranged in a direction A that is orthogonal to direction B； an accommodating part 4 for accommodating a pressing mechanism that presses the pressing surface 6b against the wrist H with direction B in a state intersecting with the direction in which the radial artery T extends, and a rotary drive mechanism for rotating the pressing surface 6b about a rotary axis X that extends in direction A and a rotary axis Y that extends in direction B, these two axes being perpendicular to the direction in which the pressing surface 6b is pressed by the pressing mechanism； a housing 101 for housing the accommodating part 4 therewithin, and a movement mechanism for moving the accommodating part 4 within the housing 101 in direction B.L'invention concerne un dispositif de détection d'ondes pulsatiles permettant d'améliorer la précision de détection d'ondes pulsatiles en faisant varier de manière souple l'état de contact entre l'élément de détection de pression utilisé en contact avec un site sur le corps humain, et le site sur le corps humain.
