Abstract

A packaging material for a cell including a laminated article having at least a coating layer, a barrier layer, and a sealant layer in the stated order, wherein: the coating layer has at least three layers including a first, second and third coating layer, and is disposed so that the first coating layer is positioned as the outermost layer and the third coating layer is positioned on the barrier-layer-side; and the first coating layer, the second coating layer, and the third coating layer are formed from a cured product of a resin composition containing a heat-curing resin and a curing accelerator so as to sufficiently exhibit a specific hardness, whereby the thickness can be reduced, exceptional chemical resistance, moldability, and inter-layer adhesion between the barrier layer and the coating layer can be obtained, and the lead time can be reduced to enable an improvement in production efficiency.
