1. A pulse wave measurement electrode unit for acquiring a volume pulse wave of an artery of a plurality of arteries of a living body by measuring a fluctuation of a biological impedance, the pulse wave measurement electrode unit comprising:

  • an electrode group including a pair of current application electrodes and a pair of voltage measurement electrodes, the electrode group to be brought into contact with a body surface of the living body during measurement; and

    a supporting member configured to support the electrode group, whereinthe electrode group includes a first electrode portion including one of the pair of current application electrodes and one of the pair of voltage measurement electrodes and (ii) a second electrode portion, positioned spaced apart from the first electrode portion, including the other one of the pair of current application electrodes and the other one of the pair of voltage measurement electrodes,the supporting member supports the electrode group such that (I) a contacting surface with respect to the living body of the first electrode portion and a contacting surface with respect to the living body of the second electrode portion are arranged substantially on an identical plane and (ii) the first electrode portion and the second electrode portion are arranged lined in a direction the artery extends when the pulse wave measurement electrode unit is brought into contact with the body surface of the living body during measurement, andeach of the pair of current application electrodes and each of the pair of voltage measurement electrodes have widths adapted to be arranged across a portion of the body surface located immediately above the artery such that only the artery of the plurality of arteries of the living body is measured.
