摘要： A method for producing a polymer piezoelectric film, comprising: a process of moving and stretching a crystalline polar polymer sheet in contact with a conductive stretching roller having a diameter of at least 30 mm and a surface friction coefficient which has been reduced to such a level as to allow a relative displacement of the crystalline polar polymer sheet in contact with the conductive stretching roller: and a step in the process of applying a polarization voltage between an electrode disposed opposite to the crystalline polar polymer sheet and the conductive stretching roller to polarize the crystalline polar polymer sheet. As a result, it is possible to stably produce a polymer piezoelectric film exhibiting stable piezoelectricity over a large area. Especially, it is possible to obtain polymer piezoelectric film exhibiting a temperature-dispersion peak temperature of d31 piezoelectricity coefficient at least 120° C. and surface scratches extending in one direction.
