Secondary battery

A secondary battery comprising:

• an electrode body which includes a positive electrode, a negative electrode, and at least one separator interposed between the positive electrode and the negative electrode;
• a case main body which receives the electrode body;
• a sealing body which seals an opening portion of the case main body;
• and
• a sealing body-side insulating member provided between the sealing body and one end portion of the electrode body and a case main body-side insulating member provided between the case main body and the other end portion of the electrode body,
• wherein the one end portion and the other end portion of the electrode body each form a protruding section which is a part of the separator protruding from the positive electrode and the negative electrode, and
• the case main body-side insulating member includes a base material and an adhesive layer which is disposed on the base material and which contains a cured object of a curable resin, and the protruding section of the other end portion is configured to be adhered to the adhesive layer such that the separator is fixed in position to the case main body-side insulating member via adhesion of said protruding section to the adhesive layer.
