ABSTRACT:
The present invention discloses a technique for inspecting a branched circuit wiring having branch portions branched halfway therefrom by using a less number of non-contact sensors. An inspection method for inspecting a branched circuit wiring having three or more ends, including the steps of: supplying an inspection signal to one end of the branched circuit wiring; disposing one or more non-contact sensors for detecting the inspection signal while being in non-contact with the branched circuit wiring over the remaining ends other than one end of the branched circuit wiring; and determining if any disconnection is caused in the branched circuit wiring, based on the inspection signal detected by the one or more non-contact sensors. The disposing step includes the step of arranging at least one of the one or more non-contact sensors to cover the remaining ends.
