1. A battery including an electrode body in which a positive electrode plate and a negative electrode plate are disposed to be opposed to each other via a separator,
wherein in each of the positive electrode plate and the negative electrode plate,
a pair of notches are formed in first and second end sides opposed to each other, and
in a third end side different from the first and second end sides, a tab extending from the third end side is formed,
wherein each of the pair of notches has a pair of opposed lateral sides and an innermost end side between the pair of opposed lateral sides, wherein the innermost end side is located inward from a corresponding one of the first and second end sides of the at least one electrode plate, and
the tab has an entire perimeter thereof at a position away and inward from the innermost end side of each of the pair of notches in a direction perpendicular to the first and second end sides of the each of the positive electrode plate and the negative electrode plate,
wherein an area of the notches formed in the positive electrode plate is greater than an area of the notches formed in the negative electrode plate,
wherein an entirety of the pair of opposed lateral sides of the notches formed in the positive electrode plate is free of overlap with the notches formed in the negative electrode plate.
