PURPOSE: An apparatus for measuring internal pressure of secondary battery is provided to measure internal pressure change of the secondary battery in a real time. CONSTITUTION: An apparatus for measuring internal pressure of a secondary battery comprises: a connection jig(410) for coupling to an electrolyte inlet of the secondary battery; a pressure gauge(420) for indicating the measured internal pressure; and a pipe(430) filled with a pressure transfer member. The connection jig comprises a protrusion(414) and sealing member(416). The sealing member is an insulator. |
