Summary:The present invention relates to a photocurable composition including: a compound having two (meth)acryloyl groups as essential components and not having a urethane bond; a compound having a photoradical polymerization initiator and one (meth)acryloyl group as an optional component and not having a urethane bond; a compound having a (meth)acryloyl group and a urethane bond; and a compound having other ethylenically unsaturated groups, wherein viscosity is 1 Pa·s or more and 100 Pa·s or less at 25℃. The curable composition is a material for forming a resin layer on at least a part of a side surface of a multilayer electrode body in an all-solid-state battery. 광경화형 조성물로서, 필수 성분인 2개의 (메타)아크릴로일기를 가지며 우레탄 결합을 가지지 않는 화합물 및 광라디칼 중합 개시제, 및 임의 성분인 1개의 (메타)아크릴로일기를 가지며 우레탄 결합을 가지지 않는 화합물, (메타)아크릴로일기와 우레탄 결합을 가지는 화합물, 및 그 밖의 에틸렌성 불포화기를 가지는 화합물을 포함하고, 점도가 25℃에서 1Pa·s 이상 100Pa·s 이하이다. 경화형 조성물은 전고체 전지에 있어서의 적층 전극체의 측면의 적어도 일부에 수지층을 형성하기 위한 재료이다.
