PROBLEM TO BE SOLVED: To provide a battery in which an electrode body, a positive internal terminal and a negative internal terminal are insulated from a battery case by an insulating film.SOLUTION: A battery 100 includes an electrode body 20 having a positive electrode and a negative electrode 60, and a battery case 30. A positive electrode internal terminal is connected to the positive electrode and a negative electrode internal terminal 90 is connected to the negative electrode 60. In the battery case 30 are provided a film A10 disposed between the electrode body 20 and the inner wall of the battery case 30, and a film B12 disposed between at least one of the negative electrode internal terminal 90 and the positive electrode internal terminal, and the battery case 30. The film A10 and the film B12 insulate the inner wall of the battery 30 and at least one of the negative electrode internal terminal 90 and the positive electrode internal terminal from each other, and insulate the electrode body 20 and the inner wall of the battery case 30 from each other.SELECTED DRAWING: Figure 5 |
