An internal pressure measuring jig for a cylindrical battery cell, of the present invention, comprises: a lower jig which has a form corresponding to a cylindrical battery cell, and has a temperature measuring part and a receiving groove in which the cylindrical battery cell is separably inserted; and an upper jig which discharges gas inside the cylindrical battery cell, has a pressure measuring part for measuring the pressure of the discharged gas, and is separably coupled to the lower jig so as to close off an opening part of the receiving groove. The internal pressure measuring jig, according to the present invention, has a gas discharge guiding part and a pressure sensor positioned in the same space, and has the temperature measuring part installed so as to come into contact with the loaded cylindrical battery cell, and thus exhibits an effect whereby the internal pressure of the cylindrical battery cell may be accurately measured by correcting the internal pressure according to temperature ...
