Abstract
A button-type secondary battery includes an electrode assembly having a first electrode with a first electrode tab and a second electrode with a second electrode tab; a can accommodating the electrode assembly and to which the first electrode tab is connected; a top cap coupled to an opening of the can and to which the second electrode tab is connected; and a first insulation member insulating the first electrode tab. The first electrode tab includes a first coupling surface coupled to the first electrode and a second coupling surface extending from the first coupling surface and coupled to the can. The first insulation member includes a first insulator attached to an outer circumferential surface of the electrode assembly to cover the first coupling surface, and a second insulator horizontally extending from an upper end of the first insulator toward a top surface of the electrode assembly.
