Abstract

A secondary battery metal terminal coating resin film having improved overall performance and capable of securing filling ability, adhesive properties, insulating properties of a lead end portion and shape retention properties of a sealant, a manufacturing method for the same and a battery pack using the secondary battery metal terminal coating resin film in provided in the lead end portion of a tab used for a laminate-type packaging material for a secondary battery. The secondary battery metal terminal coating resin film () according to the present invention is laminated, coating metal terminal () connected to a positive electrode or a negative electrode of a secondary battery. The melt flow rate of at least one layer of a resin that constitutes the resin film () is within a range from about 0.1 g/10 minutes to about 2.5 g/10 minutes.
