PROBLEM TO BE SOLVED: To facilitate the inexpensive manual switching work of a circuit to be tested in the withstand voltage test of a part requiring withstand voltage (insulating property) between circuits, for example, in circuits provided on the inside and outside of a circuit board such as printed wiring board or the like. SOLUTION: A jig having a plus pole and minus pole connectable with the lead wires drawn from the circuit to be tested is prepared. This jig is constituted so that the lead wires connected to the plus electrode and minus electrode can be manually easily replaced after connection, whereby the withstand voltage between a plurality of circuits can be tested in a short time at a low cost.
