Abstract
A battery packaging material that is excellent in continuous productivity of batteries. A battery packaging material comprising a laminate having at least a base material layer, a barrier layer, and a heat-sealable resin layer in this order, wherein the heat-sealable resin layer contains a lubricant, and when a Vickers-shaped indenter is pressed into a surface of the heat-sealable resin layer opposite to the barrier layer at a loading speed of 5 mN/10 sec, using PICODENTOR (registered trademark) HM500, in an environment at a temperature of 24° C. and a relative humidity of 50%, an indentation depth of the indenter into the heat-sealable resin layer at the point when a load on the indenter reaches 3.0 mN is 5.8 μm or less.
