Zusammenfassung:	To provide a novel polyimide film that has excellent physical properties such as transparency, mechanical property and thermal property due to the formation of an organic/inorganic hybrid, and can be applied as a cover window.SOLUTION: Provided is a polyamic acid resin, which is a polyamic acid resin obtained by containing and copolymerizing at least one diamine; at least one acid dianhydride; and polyhedral silsesquioxane (POSS), and in which at least one of the diamine and the acid dianhydride contains an alicyclic compound.SELECTED DRAWING: None 【課題】有・無機ハイブリッドの形成によって、透明性、機械的特性、熱的特性などの諸物性に優れ、カバーウィンドウとして適用できる新規なポリイミドフィルムを提供する。【解決手段】少なくとも１種のジアミン；少なくとも１種の酸二無水物；及び、多面体シルセスキオキサン（ＰＯＳＳ）；を含んで共重合されたポリアミック酸樹脂であって、上記ジアミンと上記酸二無水物のうちの少なくとも１つは、脂環族化合物を含む、ポリアミック酸樹脂である。【選択図】なし
