Abstract
A nonaqueous electrolyte battery is disclosed which is capable of realizing a sufficiently large space for accommodating a control circuit and preventing enlargement of the size thereof. The nonaqueous electrolyte battery incorporating a case constituted by a laminate film and arranged to accommodate a battery element which is enclosed by heat welding; and electrode terminal leads which are electrically connected to electrodes constituting the battery element and which are extended to the outside of the case such that the electrode terminal leads are sandwiched by a heat welded portion, wherein the nonaqueous electrolyte battery has a rectangular outer shape, two corners of one side of four sides of the nonaqueous electrolyte battery from which the electrode terminal leads extend to the outside of the nonaqueous electrolyte battery are cut, bent such that the width of each of heat welded portions corresponding to the other sides is smaller than the thickness of the nonaqueous electrolyte battery and inwards folded back along the side surface of the battery element so that a space is created and a control circuit for the nonaqueous electrolyte battery is accommodated in the space.
