ALL-SOLID-STATE BATTERY AND PHOTOCURABLE COMPOSITION USED IN ALL-SOLID-STATE BATTERY

A photocurable composition includes a compound having one (meth)acryloyl group in one molecule and not having a urethane bond and a photoradical polymerization initiator as essential components, and further includes a compound having one (meth)acryloyl group in one molecule and not having a urethane bond, a compound having a (meth)acryloyl group and a urethane bond, and a compound having another ethylenically unsaturated group as optional components, in which a viscosity of the photocurable composition at 25° C. is 1 Pa·s to 100 Pa·s. The photocurable composition is a material for forming a resin layer on at least a part of a side surface of a laminated electrode body in an all-solid-state battery.
