Abstract
A temperature sensing device for use in a secondary battery pack includes an NTC element and a current limiter element. The NTC element is disposed at a predetermined position to sense the temperature of a secondary battery incorporated in the secondary battery pack, and one end thereof is electrically connected to a temperature sensing terminal. The current limiter element is connected between the other end of the NTC element and a reference potential terminal.
