  "textContent": "Various embodiments of the present invention relate to a secondary battery. The technical problem to be solved is to provide the secondary battery which can improve the insulation strength of first and second multi-tabs, by forming the first and second multi-tabs of first and second electrode assemblies symmetrically with respect to each other, and also can improve the insulation strength of the first and second multi-tabs by forming an insulating layer on the first and second multi-tabs of the first and second electrode assemblies. To this end, disclosed is a secondary battery comprising a case; a first electrode assembly which is housed inside of the case and has a first multi-tab; a second assembly which is housed side by side with the first electrode assembly on the inside of the case and has a second multi-tab; and a cap plate which blocks the case and has an electrode terminal electrically connected to the first and second multi-tabs of the first and second electrode assemblies, wherein the first and second multi-tabs are formed symmetrically to each other with respect to a mutual boundary region of the first and second electrode assemblies, and an insulating layer is coated on the surface of the first and second multi-tabs.",
