Title
(JA) 圧電フィルム及びその製造方法
Abstract
(JA)

【課題】タッチパネルに用いられる、透明性が高く、高温下においても透明性が低下しにくい圧電フィルムを提供する。
【解決手段】透明性、特に全ヘイズ値が4.0%以下であって、100℃で24時間加熱後の全ヘイズ値変化率が10%以内である圧電フィルムであり、好ましくは、有機圧電フィルムである。有機圧電フィルムは、有機物である重合体から形成されるフィルム(重合体フィルム)である。有機圧電フィルムとしては、例えば、分極化フッ化ビニリデン系重合体フィルム、奇数鎖ナイロン圧電フィルム、及びポリ乳酸が挙げられる。有機圧電フィルムは、重合体以外の成分を含有してもよい。
