an attach portion including:
an opening provided at a position opposite a region where one artery of a wrist is found; and
an end surface that curves conforming to a shape in a circumferential direction of a portion of the wrist;

a fastener provided on the attach portion; and
a sensing body including:
a sensor unit disposed opposite the opening, the sensor unit including a sensor that comes into contact with the region where the one artery of the wrist is found and an air bag that presses the sensor toward the wrist by expanding when the blood pressure measurement device is worn on the wrist;
a case that houses the sensor in a manner allowing the sensor to move in one direction with respect to the opening, and
an elastic body that biases the sensor with respect to the wrist,

wherein the elastic body:
biases the sensor in a direction toward the wrist when an end of the sensor is located on a side of the wrist from a neutral point, the neutral point being a predetermined position respect to; and
biases the sensor in a direction away from the wrist when the end of the sensor is located at a position further away from the wrist than the neutral point.
