Abstract
A laminate cell comprises a power generating element formed by sequentially stacking positive electrode plates and negative electrode plates while interposing separators therebetween; a cell package formed of a metal composite film, the cell package hermetically sealing the power generating element and an electrolyte; a positive tab connected to the positive electrode plates; and a negative tab connected to the negative electrode plates. According to the laminate cell, the power generating element and the cell package have approximately rectangular plane shapes, and the positive tab and the negative tab are drawn outward from end edges of long sides of the cell package.
