Rectangular secondary battery

A rectangular secondary battery, comprising:

• a rectangular casing that has an opening;
• a sealing plate that seals the opening;
• an electrode body that is disposed in the rectangular casing and that includes at least one positive electrode plate and at least one negative electrode plate;
• a plurality of tabs that are connected to the at least one positive electrode plate or the at least one negative electrode plate;
• a current collector that is connected to the plurality of tabs;
• and
• a terminal that is electrically connected to the current collector and that protrudes from the sealing plate toward an outside of the battery,
• wherein a first tab group that is composed of a plurality of the plurality of tabs and a second tab group that is composed of a plurality of the plurality of tabs are connected to the electrode body,
• wherein the first tab group and the second tab group are disposed between the sealing plate and the electrode body,
• wherein the first tab group and the second tab group are disposed so as to be displaced from each other in a longitudinal direction of the sealing plate, and
• wherein the first tab group and the second tab group are connected to different positions on the current collector.
