Abstract

A roll electrode is provided with a core, an electrode, a fixing part and a regulating part. The core extends in an axial direction and has a substantially circular outer circumference. The electrode has an expansion coefficient lower than that of the core. The electrode wound into a roll shape on the outer circumference of the core. The fixing part is fixed to an end portion from which the electrode starts being wound around the core. The regulating part regulates the axial movement of the electrode wound into the roll shape with respect to the core.
