Device and method for inspection

An inspection method for inspecting a circuit wiring of a circuit board, said inspection method comprising the steps of:

• disposing a conductive member on the side of one of the surfaces of said circuit board, said conductive member being adapted to be supplied with an inspection signal;
• disposing a plurality of cells on the side of the other surface of said circuit board with opposing to said conductive member;
• supplying the inspection signal to said conductive member;
• and
• acquiring each signal appearing at said cells in response to said inspection signal applied to said conductive member.

An inspection apparatus for inspecting a circuit wiring of a multilayer circuit board having an overall electrode layer, said inspection apparatus comprising:

• means for supplying an inspection signal to an overall electrode of said overall electrode layer;
• a plurality of cells adapted to be disposed on the side of at least either one of the surfaces of said circuit board with opposing said overall electrode;
• and
• means for acquiring each signal appearing at said cells in response to said inspection signal applied to said overall electrode.
