Abstract
A secondary battery in which the contact resistance is not increased even if the number of housed electrodes is increased is provided. Two screw holes 11d are formed in an opposed surface 11c of a terminal body portion 11b of a positive terminal 11 that faces the stacking direction. A projecting surface 11e is provided between the two screw holes 11d to project toward a positive pressing member 25 with respect to portions provided with the screw holes 11d. The projecting surface 11e projects toward the positive pressing member 25 by 0.2 mm with respect to the portions provided with the two screw holes 11d.
