Lead for nonaqueous electrolyte battery

A lead for a nonaqueous electrolyte battery, the lead comprising:

• a conductor having a plate shape and having an upper surface and a lower surface each having a rectangular shape;
• a first electrically insulating resin film disposed at the upper surface of the conductor;
• and
• a second electrically insulating resin film disposed at the lower surface of the conductor,
• wherein, with the conductor being viewed in a direction perpendicular to the upper surface, when an axis extending along selected two sides of the conductor is defined as an X-axis, the selected two sides facing each other, and an axis orthogonal to the X-axis is defined as a Y-axis,
• the first electrically insulating resin film and the second electrically insulating resin film are disposed so as not to cover two end portions of the conductor in a direction along the Y-axis and are disposed so as to extend along the X-axis and cross and cover, at a portion of the conductor other than the two end portions, the conductor and so as to overlap each other when viewed in the direction perpendicular to the upper surface,
• wherein at least one of the first electrically insulating resin film and the second electrically insulating resin film has a first film layer and a second film layer in order from a location closer to the conductor, and
• wherein the second film layer is disposed such that a portion of a surface of the first film layer is exposed, and a type of a resin in the second film layer differs from a type of a resin in the first film layer.
