Beschreibung
Zusammenfassung:	A sealing apparatus for a secondary battery according to the present invention is a sealing apparatus for sealing a battery case, which accommodates an electrode assembly therein, to manufacture the secondary battery. The secondary battery comprises an electrode lead which is connected to the electrode assembly and extended to the outside of the battery case, and the battery case comprises: a lead sealing portion in which the electrode lead is located in a pressing direction at an outer circumferential surface; and a case sealing portion in which only the battery case is located. The sealing apparatus comprises: a pair of sealing blocks which press the outer circumferential surface of the battery case; and a heating unit which is provided in the pair of sealing blocks and heat the pair of sealing blocks. The pair of sealing blocks comprise: lead sealing regions configured to press the lead sealing portion of the battery case; and case sealing regions configured to press the case sealing portion of the battery case. The heating unit heats the lead sealing regions and the case sealing regions of the pair of sealing blocks at different temperatures.
