Abstract
Disclosed is a laminate for non-aqueous secondary battery which includes a water-soluble polymer-containing functional layer and an adhesive layer adjacently disposed on the functional layer, and which can suppress reductions in peel strength of a battery member including the laminate while allowing the functional layer to exert its expected function. The disclosed laminate includes a functional layer containing functional particles and a water-soluble polymer, and an adhesive layer adjacently disposed on the functional layer, wherein a film obtained by shaping of the water-soluble polymer has a water drop contact angle of 30° to 80°.
