PROBLEM TO BE SOLVED: To easily analyze how much test current flows to cause FAIL determination when the FAIL is determined in a withstand voltage test. SOLUTION: A test voltage value, testing time, a threshold Ib of test current used as an acceptance determination reference, and a test stop current value Ic larger than the threshold Ib can be set to a control section 13 from an input section 14. When the test current Ia flowing in a tested object EUT is smaller than the threshold Ib during the test, a first routine of outputting the acceptance determination to a display section 15 is executed after the lapse of the testing time. When the test current Ia is larger than the test stop current value Ic, a second routine of stopping the test at that time and outputting fail determination to the display section 15 is executed. When the test current Ia is larger than the threshold Ib and smaller than the test stop current value Ic, the test is continued until the testing time is finished and a third routine of outputting fail determination to the display section 15 is executed.
