<p>A circuit wiring branching in the middle thereof is inspected by using fewer non-contact sensors. A method of inspecting a branched circuit wiring having at least three ends, comprising the supply step of supplying an inspection signal to one end of the branched circuit wiring, the disposing step of disposing non-contact sensors that detect the inspection signal without contacting the branched circuit wiring at the other ends of the wiring, and the judging step of judging whether or not the wiring is disconnected based on the inspection signal detected by the non-contact sensors, characterized in that the disposing step allocates the other two ends to at least one non-contact sensor, and the judging step compares a specified threshold with the strength of the inspection signal detected by the non-contact sensors to which the other two ends are allocated to judge whether the wiring is disconnected or not.</p> |
