Provided is a method for manufacturing a weak current tool, by which a simple structure and common materials are used to manufacture a weak current tool that has a thin electrode structure and is easy to use. The method is for manufacturing a weak current tool that is used in contact with skin and that includes: a first electrode part which is a sheet-shaped weak current sheet and which is made of a first electrode material having a first metal as a primary component thereof； a second electrode part which is made of a second electrode material having a second metal that has a difference in potential with the first metal as a primary component thereof, and which is electrically connected to the first electrode part； and a first insulating part which is made of an insulating material and insulates the first electrode part and the second electrode part from each other on the skin contact surface. The method for manufacturing the weak current tool includes: an electrode bonding material manufacturing step for manufacturing an electrode bonding material that includes the first electrode material and the second electrode material； a punching out step for obtaining a plurality of electrode bonding sheets by punching out one of the electrode bonding materials into a prescribed shape a plurality of times； and an insulating material installing step for installing the insulating material on the electrode bonding sheets.La présente invention concerne un procédé de fabrication d'un outil à courant faible, par lequel une structure simple et des matériaux communs sont utilisés pour fabriquer un outil à courant faible qui a une structure d'électrode mince et est facile à utiliser.
