Disclosed is a rectangular battery in which an electrode group formed by winding a first electrode and a second electrode with a separator interposed therebetween is housed in a battery case having an opening sealed by a sealing plate. The first electrode is electrically connected to the sealing plate, and the second electrode is electrically connected to a current collector plate provided between the sealing plate and the electrode group and extending along a longer side direction of the sealing plate. The sealing plate has a lower-strength portion configured to be deformed prior to the other portions of the sealing plate to provide a contact between the sealing plate and the current collector plate when the sealing plate receives an external pressure along the longer side direction of the sealing plate.
