An electrode for measuring a bio potential includes a conductive adhesive having one side configured to have at least two metal electrodes attached thereto while the electrode is being used, and another side configured to be attached to a living body while the electrode is being used, the conductive adhesive having a predetermined area and a predetermined thickness； and a supporting element configured to support the conductive adhesive while the conductive adhesive is attached to the living body； wherein an impedance is formed between the at least two metal electrodes while the at least two metal electrodes are attached to the side of the conductive adhesive, the impedance depending on a thickness of the conductive adhesive and having a value that prevents the at least two metal electrodes from being shorted together.
