All-solid-state battery and photocurable composition used in all-solid-state battery

A photocurable composition for an all-solid-state battery, the photocurable composition comprising:

• a first component, a fifth component, a second component, and a third component, wherein:
• the first component is a compound with having two (meth)acryloyl groups in one molecule and not having a urethane bond, and a number average molecular weight of 1000 or higher;
• the second component is a compound having one (meth)acryloyl group in one molecule and not having a urethane bond;
• the third component is a compound having one or more (meth)acryloyl groups and one or more urethane bonds in one molecule;
• the fifth component is a photoradical polymerization initiator;
• a total content ratio of the first component and the second component is 60 wt % to 100 wt %;
• a content ratio of the third component is lower than 40 wt %;
• when the total content of the curable components is represented by 100 parts by weight, a content ratio of the fifth component is 0.01 parts by weight to 10 parts by weight;
• a viscosity of the photocurable composition at 25° C. is 1 Pa·s to 100 Pa·s;
• the all-solid-state battery includes a laminated electrode body in which electrode bodies are laminated, each of the electrode bodies including a positive electrode, a negative electrode, and a solid electrolyte layer containing a sulfur material, the positive electrode and the negative electrode being laminated via the solid electrolyte layer;
• and
• the photocurable composition is a material for forming a resin layer made of a resin cured product, on at least-outer circumferential side surfaces of the laminated electrode body.
