An object of the present invention is to provide a battery that can be readily fabricated, and further, can suppress movement of an electricity-generating element. A battery 100 is provided with an electricity-generating element 2 that is formed by winding a positive electrode 21, a negative electrode 22, and a separator 23 and has a winding axial portion 25, and a spacer 8 having an inclined portion 83 having a width that is gradually reduced toward an end, wherein the spacer 8 is inserted into the winding axial portion 25 of the electricity-generating element 2 at the tip of the spacer 8, so that the inclined portion 83 presses the electricity-generating element 2. |
