Abstract:
1. A continuity inspection apparatus for inspecting electrical continuity between first and second terminals of a pattern wire formed on a board, said continuity inspection apparatus comprising: first capacitive coupling means to be capacitively coupled with said first terminal in a non-contact manner to provide a coupling capacitance therebetween; an inductive element connected to said first capacitive coupling means to form a resonance circuit in conjunction with the capacitance yielded by said first capacitive coupling means; a first lead wire connected to said inductive element; second capacitive coupling means connected to a second lead wire and to be capacitively coupled with said second terminal in a non-contact manner to provide a coupling capacitance therebetween; signal inputting means for inputting an inspection signal including an AC component into one of said first and second lead wires; and signal detecting means for detecting an output of said inspection signal at the other of said first and second lead wire.
