Abstract
In a circuit board testing apparatus for performing a four-terminal measurement method on a wiring pattern formed of a plurality of wires on a circuit board, a control part connects in series contact probes to be connected to upstream-side voltage detection terminals or downstream-side voltage detection terminals, via connection terminals, allows a power supply part to apply power between the test points with which the contact probes connected in series are in contact, allows a voltage detection part to detect a voltage between the test points, and makes a determination as to conductive contact states of the contact probes with the test points, based on the detected voltage.
