Summary:To provide a novel piezoelectric resin film superior in piezoelectric property.SOLUTION: A piezoelectric resin film comprises at least a piezoelectric resin and a silane-based compound, and has a crystal structure in which a granular crystal substance is dispersed isotropically. The size of the granular crystal substance is larger than 0.1 μm and smaller than 10 μm. The degree of crystallization of the crystal structure is larger than 50% and smaller than 80%.SELECTED DRAWING: Figure 2 【課題】圧電特性に優れた新規な圧電性樹脂膜を提供する。【解決手段】圧電性樹脂膜は、少なくとも圧電性樹脂とシラン系化合物とを含み、粒状の結晶体が等方的に分散した結晶構造を有する。粒状の結晶体のサイズは、０．１μｍよりも大きく１０μｍよりも小さい。また、結晶構造の結晶化度は、５０％よりも大きく８０％よりも小さい。【選択図】図２
