PROBLEM TO BE SOLVED: To provide a circuit inspection device capable of surely and easily detecting defects of a circuit board. SOLUTION: An inspection signal is supplied from a feed part 30 capacity- coupled to conductor patterns 20, arranged in line to one of the conductive patterns 20, the inspection signal is detected by an open sensor 40 capacity- coupled to all other end parts of the line conductor patterns 20, and a pattern disconnection is determined, when the output is largely reduced. The inspection signal is also detected by a short sensor 50 offset to the feed part 30 and capacity-coupled to the pattern parts of two lines of the line conductor patterns 20, and a pattern is determined as having disconnection, when the detection signal is raised or lowered by a large amount, whereby the quality of the pattern is inspected.
