The objective of the present invention is to a curable composition which has high transparency, is difficult to reduce transparency when heated, and can form a cured product having excellent organic solvent resistance, a cured product thereof, and a method for manufacturing a cured film using the same. According to the present invention, the curable composition comprises: a polymerizable compound (A); metal oxide fine particles (B) containing titanium oxide fine particles (B1); an initiator (C); and a solvent (S). The polymerizable compound (A) is a polymerizable fluorene compound (A1) having a radical polymerizable group-containing group or a cationic polymerizable group-containing group and having a fluorene skeleton, and the initiator (C) is a heat-sensitive initiator (C1). [과제] 투명성이 높음과, 가열되었을 경우의 투명성의 저하하기 어려움과, 뛰어난 유기 용매 내성을 겸비하는 경화물을 형성할 수 있는 경화성 조성물과, 당해 경화성 조성물의 경화물과, 당해 경화성 조성물을 이용하는 경화막의 제조 방법을 제공하는 것. [해결 수단] 중합성 화합물(A)과, 산화 티탄 미립자(B1)를 포함하는 금속 산화물 미립자(B)와, 개시제(C)와, 용매(S)를 포함하는 경화성 조성물에 있어서, 중합성 화합물(A)로서, 라디칼 중합성기 함유기, 또는 양이온 중합성기 함유기를 갖고, 또한 플루오렌 골격을 가지는 중합성 플루오렌 화합물(A1)을 이용하고, 개시제(C)로서, 감열성 개시제(C1)를 이용한다.
