PROBLEM TO BE SOLVED: To provide a method of manufacturing a strip electrode capable of reducing distortion of a current collector foil while preventing an uncoated part from being creased.SOLUTION: A large diameter part 35 of a stretching roll 30 has an enlarged diameter part 36 adjacent to a small diameter part 31, the diameter of the enlarged diameter part 36 being enlarged as it goes away from the small diameter part 31 with respect to the axial direction of the stretching roll 30. The peripheral surface 36b of the large diameter part 36 forms an arc shape projecting outward while enlarging the diameter thereof, forms a tapered shape in which a length L of the bus bar is made not less than a width dimension W of the uncoated part, or has a shape in which the tapered part and the arc-shaped part projecting outward enlarges the diameters thereof while being arranged in this order from the small diameter part 31 side with respect to the axial direction of the stretching roll 30. |
