According to the present invention, a battery element is accommodated in a packaging material made of a laminate film, and is sealed by thermal fusion, and at the same time, an electrode terminal lead connected to each electrode constituting the battery element is inserted into a heat fusion portion to be exposed to the outside of the packaging material. In an electrolyte cell,n n n The electrode terminal lead is covered with a sealant resin at a position corresponding to the heat-sealed portion,n n n The sealant resin in contact with at least one main surface of the electrode terminal lead is deformed according to the shape of the electrode terminal lead, and relates to a nonaqueous electrolyte battery, characterized in that it is uneven. |
