Abstract: A film-shaped packaging material for a cell in which a coating layer is provided as the outermost layer instead of a substrate layer and an adhesive layer in a conventional film-shaped packaging material for a cell, thereby making it possible to produce a thinner film; wherein the packaging material is provided with exceptional moldability and insulation performance and enables lead time to be reduced. The packaging material is a laminate having at least a coating layer, a barrier layer, and a sealant layer in the stated order, the coating layer including a single- or multiple-layer configuration formed by a cured product of a resin composition containing a heat-curable resin and curing accelerator, the laminate having a piercing strength of at least 5 N, as measured in compliance with JIS 1707:1997, and the coating layer having a breakdown voltage of at least 1.0 kV, as measured in compliance with JIS C2110-1.
