An electrode terminal provided at an upper end of a high-temperature secondary battery which is disposed in a frame provided at an upper opening of an inspection furnace in which a high-temperature secondary battery is housed and which is carried into the inspection furnace. An opposing electric connection jig for a high-temperature secondary battery, a fixing jig main body fixed to the frame and protruding downward and connected to a conductive member, and rotatably assembled to the fixing jig main body. A movable jig body that protrudes downward and forms a connection terminal for holding the electrode terminal of the high-temperature secondary battery together with the lower end protrusion of the fixing jig body at the lower end protrusion, and is interposed between these two jig bodies; A spring member that separates the lower end protruding portion of the movable jig body from the lower end protruding portion of the fixed jig body; By operation, the lower end protruding portion of the movable jig main body is fixed to the fixed jig against the spring member. Electrical connecting jig for high temperature secondary battery characterized by comprising a screw member for rotating the lower projecting portion of the main body. 2. The electric connection jig for a high-temperature secondary battery according to claim 1, wherein said high-temperature secondary battery is lifted up in a state where said movable jig main body is separated from said fixed jig main body. The electrode terminals of the high-temperature secondary battery are located between the lower end protruding portions of the two jig bodies, and the screw terminal of the screw member causes the electrode terminals of the high-temperature secondary battery to be at the lower protruding portions of the two jig bodies. An electric connection jig for a high-temperature secondary battery, which is sandwiched. 3. The electric connection jig for a high-temperature secondary battery according to claim 1, wherein a conductive member for introducing and outputting a current is connected to the fixing jig main body side, and a lower end of the movable jig main body. An electrical connection jig for a high-temperature secondary battery, wherein a conductive member for introducing and outputting a voltage is connected to a tip of the protrusion.
