An electrodeposition coating using an electrodeposition coating composition based on a synthetic resin makes it possible to easily and easily form a film having a uniform thickness with no unevenness in detail, and has good electrical insulation. A battery case, a battery including the battery case, and a nonaqueous electrolyte secondary battery are provided. In a nonaqueous electrolyte secondary battery in which a positive electrode, a negative electrode, and an electrolyte are accommodated in a battery case, an insulating coating is formed on the inner surface of the battery case. The insulating coating 11 is formed by electrodeposition-coating a battery case 6 with an electroactive electrodeposition coating composition having an epoxy resin as a skeleton and a resin containing a sulfonium group as a hydrated functional group as a base resin.
