Zusammenfassung:	The present invention relates to a method for manufacturing a lead tab for a secondary battery, which can include the steps of: supplying a lead tab; forming a concave-convex pattern by irradiating laser light onto a predetermined area of the lead tab; and attaching an insulating film to the concave-convex pattern. In the step of forming a concave-convex pattern, a first concave-convex pattern is formed by irradiating first laser light to a first area of the front surface of the lead tab, and a second concave-convex pattern can be formed by irradiating second laser light to a second area of the rear surface of the lead tab. 이차전지용 리드탭 제조 방법에 관한 것으로, 리드탭을 공급하는 단계, 상기 리드탭의 소정영역에 레이저 광을 조사하여 요철 패턴을 형성하는 단계, 그리고 상기 요철 패턴 위에 절연 필름을 부착하는 단계를 포함할 수 있다. 상기 요철 패턴을 형성하는 단계는, 상기 리드탭 전면의 제1 영역에 제1 레이저 광을 조사하여 제1 요철 패턴을 형성하고, 상기 리드탭 후면의 제2 영역에 제2 레이저 광을 조사하여 제2 요철 패턴을 형성할 수 있다.
