Zusammenfassung:Disclosed is a composition for a non-aqueous secondary battery adhesive layer which comprises a particulate polymer, wherein a value of pressure sensitivity of adhesion strength as obtained using the following formula (1) is greater than 20 and less than 80: pressure sensitivity of adhesion strength (N/(m·MPa)) = (T3-T1)/2 ... (1), where T1 represents an adhesion strength (N/m) between a polyethylene separator and an adhesive layer for a non-aqueous secondary battery adhesive layer that is obtained from the composition for a non-aqueous secondary battery adhesive layer when the polyethylene separator and the adhesive layer are bonded by pressing at 25°C and a pressure of 1 MPa for 10 seconds, and T3 represents an adhesion strength (N/m) between the polyethylene separator and the adhesive layer when the polyethylene separator and the adhesive layer are bonded by pressing at 25°C and a pressure of 3 MPa for 10 seconds.
