ABSTRACT:
A can type secondary battery. The can type secondary battery has a fixing unit for fixing an end portion of a terminal plate to an end portion of an insulation plate of a cap assembly in order to prevent a short circuit between the terminal plate and an electrode assembly by preventing the terminal plate from being deformed due to external force or external pressure applied to the can type secondary battery, thereby improving safety of the secondary battery.
