ELECTRODE ROLL AND METHOD FOR PRODUCING ELECTRODE ROLL

To provide an electrode roll capable of preventing lowering of production efficiency due to active material particles that have fallen. An electrode roll (600) in which a sheet-like electrode base material (500) which is subjected to cutting to be an electrode used for an electrochemical element is rolled, including a resin cylindrical member (200) having a peripheral surface (220) with a predetermined width, a flexible film (400) to be attached/detached with respect to the peripheral surface, and the sheet-like electrode base material (500) wound on the flexible film (400).
