Beschreibung
Zusammenfassung:	An adhesive film for metal terminals, which is to be interposed between a metal terminal connected to an electrode of a battery element and a packaging material for sealing the battery element, the adhesive film for metal terminals comprising a first polyolefin layer, a base material film, which is a stretched film containing polyethylene naphthalate, and a second polyolefin layer in this order, wherein at least one of the first and second polyolefin layers contains an acid-modified polyolefin, and when infrared absorption spectra are obtained for a surface of the base material film in a direction perpendicular to a thickness direction, in 18 directions from 0°, which is an arbitrary reference direction, to 170°, in increments of 10°, by means of polarization measurement by Fourier transform infrared spectroscopy using single-reflection ATR, a value obtained by calculating, in each of the 18 directions, a value Y by dividing an absorption peak intensity Y765at 765 cm-1by an absorption peak intensity Y1181at 1181 cm-1in the infrared absorption spectrum, and then by dividing a maximum value Ymaxof the values Y by a minimum value Yminof the values Y, is 1.0 or more and 1.3 or less.
