PROBLEM TO BE SOLVED: To provide a bio-battery treatment tool capable of effectively flowing an electric current even if the negative electrode is long and has a high resistance value, resulting in a good skin contact feeling and an excellent current stimulation effect. SOLUTION: A negative electrode constituent member (11) and a positive electrode constituent member (12) are connected to a conductive member (13) to bring the negative electrode constituent member (11) and the positive electrode constituent member (12) into contact with the skin. By doing so, a bio-battery treatment tool for forming an energization circuit in the skin, wherein the conductive member (13) is a surface facing the skin contact surface of the negative electrode constituent member (11), and a positive electrode constituent member ( The negative electrode constituent member (11) and the positive electrode constituent member (12) are bridge-connected between the skin contact surface of 12) and the opposite surface.
