The embodiment provides a control unit for measuring living body information on the basis of pressure pulse waves detected by pressure sensors in a state that the pressure sensors are pressed toward a radius artery by an air bag and display units which are arranged around a wrist in the state that the pressure sensors are pressed toward the radius artery. The control unit performs display controls on the display units. One of the display units is disposed on the palm side of the wrist in the state that the pressure sensors are pressed toward the radius artery. The other one of the display units is disposed on the hand back side of the wrist in the state that the pressure sensors are pressed toward the radius artery.
