PROBLEM TO BE SOLVED: To provide a device capable of measuring a variation in distance between an electrode and a person, a contact state caused by the person's motion, or the like concurrently with biological information measurement using the electrode.SOLUTION: A biological information measurement device comprises: three biological signal measurement electrodes 01 composed of a first electrode 02 and second electrode 03 that make a pair of differential electrodes provided on a person through an insulator or directly on the person's skin, and a third electrode 04 that is an electrode for inducing intermediate potential; a transmission electrode for transmitting a signal to the person's living body as means for communication through the living body; measurement means for detecting, as an electrocardiographic signal, potential between the pair of differential electrodes taking induced potential at the intermediate electrode as a reference, and means for detecting a signal of the transmission electrode received from the first electrode and second electrode through the living body; and transmission wave generation means for generating a transmission signal to be induced at the transmission electrode.SELECTED DRAWING: Figure 1 |
