PROBLEM TO BE SOLVED: To provide a burn-in apparatus comprising a means for easily detecting a contact condition between a power source terminal and a ground terminal of an IC and an IC socket. SOLUTION: A contact condition confirming wiring 3 for connecting power source/ground terminals 12 and 13 of each IC socket 4 in series, a voltage source 6 for applying a specified voltage to the wiring, and an ammeter 7 for measuring a current flowing in the wiring when a specified voltage is applied from the voltage source 6, are provided. Switches 8 and 9 are provided for switching between connecting to the power source/ground terminals 12 and 13 of each IC socket 4 to a power source voltage supply line 1 and a ground voltage supply line 2 and for connecting it to the contact quality confirming wiring 3. At detecting a contact condition, the switches 8 and 9 are switched over to the side of the contact quality confirming wiring 3 for supplying a specified voltage from the voltage source 6. A prescribed current flows if there is good contact, while no current will flow if there is poor contact. Thus, the quality of terminal contact is easily detected.
