<p>PROBLEM TO BE SOLVED: To provide a laminate in which decrease in a production yield due to scratches on a polymeric piezoelectric film or intrusion of foreign substances is decreased in an intermediate process upon manufacturing a press-detection device or a device using the press-detection device.SOLUTION: The laminate includes the following polymeric piezoelectric film 10, a conductive layer (for example, an electrode 14A) disposed on one major surface of the polymeric piezoelectric film 10, and a protective film 16 that is removable and disposed on the other major surface of the polymeric piezoelectric film 10. The polymeric piezoelectric film 10 contains a helical chiral polymer (A) having optical activity and a weight average molecular weight of 50000 to 1000000, and has a crystallization degree of 20% to 80% obtained by a DSC method, in which a product of the crystallization degree and a normalized molecular orientation MORc measured by a microwave transmission type molecular orientation meter in a reference thickness of 50μm is 40 to 700.</p> |
