Abstract: An electrode sheet is flexibly adapted to the position where a signal is acquired. The electrode sheet is attached to a living body and acquires a biological signal, and is provided with a sheet-form biological signal acquisition unit, which is attached to a living body part where a biological signal is acquired. A reference potential acquisition unit extends from the living body signal acquisition unit and is attached to a living body part where a reference potential is acquired. The reference potential acquisition unit is provided with multiple electrodes, which are arranged at a prescribed interval along the direction of extension. Each of the electrodes can attach to the living body part where the reference potential is acquired.
