1. A bioimpedance measurement device, the device comprising:
a body part configured to accommodate a measurement circuit, the body part including a grip that can be gripped by a hand;
a first electrode and a second electrode coupled to a first shaft provided on one side of the body part, the first electrode and the second electrode configured to rotate about the first shaft; and
a third electrode and a fourth electrode coupled to a second shaft provided on the one side of the body part at a position different from that of the first shaft, the third electrode and the fourth electrode configured to rotate about the second shaft,
wherein the device is configured to measure a bioimpedance of a subject to be measured when the subject to be measured approaches, and is surrounded by and comes into contact with the first electrode, the second electrode, the third electrode, and the fourth electrode, and
wherein the measurement circuit is configured to determine that the bioimpedance measurement result is not valid when at least one of the second electrode and the fourth electrode rotates to a limit toward the grip and is pressed, while being pressed by the subject to be measured.
