Disclosed is an organic piezoelectric material film which has little contaminants and has excellent piezoelectric properties. The organic piezoelectric material film is produced by a solution casting process using, as raw materials, a raw material for an organic piezoelectric material and a crushed product which is produced by crushing a material produced by a solution casting process and is mainly composed of an organic piezoelectric material. L'invention concerne un film en matériau piézoélectrique organique qui comporte peu de contaminants et qui possède d'excellentes propriétés piézoélectriques. Le film en matériau piézoélectrique organique est produit selon un processus de coulage de solution en utilisant, en qualité de matières premières, des matières premières pour un matériau piézoélectrique organique et un produit broyé qui est produit en broyant un matériau produit selon un processus de coulage de solution et qui se compose principalement d'un matériau piézoélectrique organique.
