PROBLEM TO BE SOLVED: To provide a test burn-in device which realizes a self diagnostic test in a low-temperature or high-temperature state and also enables a simpler self diagnostic test. SOLUTION: A diagnostic unit 21 is provided in a test control part 20 and is connected with driver/comparator circuits 26 through a connecting cable in a thermostat 10. Moreover, the cable 11 in the tank 10 is constituted of a heat-resistant material, is connected with the unit 21 via a diagnostic unit connecting connector 14 by a connector 12 for the unit 21 and is connected with the circuits 26 via burn-in board connecting connectors 15 by a connector 13 for a burn-in board.
