PURPOSE:To contact-bond a radiator plate and a test element by providing a drive means for testing the test element provided with a heat sink plate, in which a magnet is buried, and a contact. CONSTITUTION:A permanent magnet 6 is buried in a radiator plate 3. A socket 4 conducting a connection to a test element 2 is mounted just under the test element 2. When the test element 2 is inserted to the socket 4, the test element 2 is sucked by the suction force of the permanent magnet 6 buried to the heat sink plate 3, and the test element 2 is fixed to the radiator plate by the action of the permanent magnet 6. The test element 2 is coupled with a circuit for drive in a printed circuit 5 under said state, and the characteristics of the test element 2 can be tested. |
