To provide a partition wall having excellent ink repellency on an upper surface and excellent pro-ink property on a side surface, a method of restoring a partition wall and an optical element having a partition wall.SOLUTION: A method of restoring a partition wall includes a step of forming a hardened film of a shape corresponding to the partition wall and having an upper surface and a side surface continuous to it by applying and hardening a partition wall hardening composition having a unit having a fluoro alkyl group, an oxime group and a cross-linking functional group and containing a liquid-repellency compound (A), a cross-linking agent (B) and a polymerization initiator (C) which become lyophilic by radiation of an ultraviolet ray with a wavelength of 300 nm or more by minute quantity discharging, and a step of forming a pro-liquidity area on a side surface of the hardened film by applying light to the side surface. A recovered partition wall and an optical element having a partition wall are also provided.SELECTED DRAWING: Figure 1 【課題】上面が良好な撥インク性を有し、側面が良好な親インク性を有する隔壁、隔壁の修復方法、及び隔壁を備えた光学素子を提供する。【解決手段】フルオロアルキル基、オキシム基、及び架橋性官能基を有する単位を有し、波長３００ｎｍ以上の紫外線の照射によって親液化する撥液性化合物（Ａ）と、架橋剤（Ｂ）と、重合開始剤（Ｃ）とを含有する隔壁用硬化性組成物を微量吐出法用により塗布し硬化させて、前記隔壁に対応する形状の、上面とそれに続く側面を有する硬化膜を形成する工程と、前記硬化膜の側面に光を照射して、前記側面に親液性領域を形成する工程とからなる、隔壁の修復方法、修復された隔壁、および該隔壁を有する光学素子。【選択図】図１
