Abstract

The present invention describes a component for a secondary battery and a manufacturing method thereof, and a secondary battery manufactured by using the component. The component for a secondary battery according to the present invention comprises a lead-free soldering bridge having a melting point of 150 to 300° C. and containing tin (Sn) and copper (Cu) as a main ingredient; the first and second metal plates spaced therebetween through a gap and coupling with the lead-free soldering bridge. According to the present invention, when an over-current flows through the component for a secondary battery, the temperature of the lead-free soldering bridge is locally increased rapidly to melt the lead-free soldering bridge, thereby efficiently interrupting the flow of an over-current.
