Disclosed is a separator provided with an adhesive porous layer containing a polyvinylidene fluoride resin. The separator has good adhesiveness to an electrode by a dry heat press, and further has adhesiveness with an electrode after immersion in an electrolyte solution And an excellent non-aqueous secondary battery separator. As means for solving such a problem, there is a porous substrate, and an adhesive porous layer formed on one or both surfaces of the porous substrate and including a polyvinylidene fluoride resin, (2) a resin containing a hydroxyl group or an amino group, (1) a resin containing a carboxylic acid anhydride and / or a carboxylic acid anhydride as a monomer component, and (2) a resin containing a hydroxyl group or an amino group. |
