Provided are a control unit 12 for measuring living body information on the basis of pressure pulse waves detected by pressure sensors 6a and 7a in a state that the pressure sensors 6a and 7a are pressed toward a radius artery T by an air bag 2 and display units 104 and 105 which are arranged around a wrist in the state that the pressure sensors 6a and 7a are pressed toward the radius artery T. The control unit 12 performs display controls on the display units 104 and 105. The display unit 104 is disposed on the palm side of the wrist in the state that the pressure sensors 6a and 7a are pressed toward the radius artery T. The display unit 105 is disposed on the hand back side of the wrist in the state that the pressure sensors 6a and 7a are pressed toward the radius artery T.
