높은 굴절률 및 높은 투명성을 갖는, 패터닝 된 박막을 단시간에 용이하게 제조할 수 있는 제조 방법, 및 그 방법으로 제조된 고 굴절률 박막의 제공. 제1공정：하기 식(1)로 나타내어지는 인 화합물로 수식된 금속 산화물 함유 졸(sol)으로 기판상에 도막을 형성하는 공정, (식(1) 중, R는 수소 원자, 알킬기, 알키닐기, 알케닐기, 아릴기, 지방족복소환기, 또는 방향족복소환기이며, R는 2가의 유기잔기이며, n는 1 또는 2이다.) 제2공정：제1공정에서 얻어진 기판상의 도막을, 빛을 조사하여 경화시키는 공정, 및 제3공정：제2공정에서 얻어진 경화물에 추가적으로 가열 및/또는 빛의 조사에 의해 에너지를 더하는 공정, 을 포함하는 박막의 제조 방법. Provided are a method for easily and quickly producing a patterned thin film having a high refractive index and a high transparency, and a highly refractive thin film produced by the method. The method comprises a first step: a step of forming, on a substrate, a coating using a sol containing a metal oxide modified with a phosphorus compound represented by the following formula (1): (wherein R 1 is a hydrogen atom, an alkyl group, an alkynyl group, an alkenyl group, an aryl group, an aliphatic heterocyclic group, or an aromatic heterocyclic group; R 2 is a divalent organic residue; and n is 1 or 2) ; a second step: a step of curing the coating on the substrate obtained in the first step by light irradiation; and a third step: a step of further adding energy to the cured film obtained in the second step by heating and/or light irradiation.
