    摘要： Disclosed are a current interrupting device and a secondary battery including the same. According to an embodiment, a current interrupting device (10) comprises a first terminal (11); a second terminal (12); a fuse coupled (13) to the first and second terminals; and a fuse body (14,15) surrounding an exterior of the fuse to seal the fuse, wherein the first and second terminals include thin portions (11b,12b) connected to the fuse, and the thin portions have a thickness less than a thickness of other portions of the first and second terminals. The current interrupting device interrupts a current when the temperature of the battery is excessively increased or when the voltage of the battery is quickly increased by overdischarge or overcharge of the battery, thus preventing accidents such as battery explosion.
