<p>Even when a coaxial cable in which a capacitor is built is tested, an entire part of the cable can be tested by a simple operation without breaking down the capacitor. A high voltage testing device uses as an object to be inspected a coaxial cable (11) including a core wire (11a) and an insulated shield conductor (11b) and applies a high voltage thereto to carry out a test of an electric insulation state. The high voltage testing device includes a jig for a high voltage test (20) that connects two output electrodes (31, 32) of an output of a tester which outputs a high voltage respectively to the central conductor and the shield conductor of the coaxial cable as the object to be inspected. The cable connecting part includes a core wire short-circuiting part (P1) which electrically short-circuits between one and the other end in the longitudinal direction of the core wire (11a) of the coaxial cable and a shield wire shirt-circuiting part (P2) which electrically short-circuits between one end and the other end in the longitudinal direction of the shield conductor (11b) of the coaxial cable.</p> |
