PROBLEM TO BE SOLVED: To provide a circuit board inspection device capable of detecting surely a short circuit between conductor patterns. SOLUTION: This circuit board inspection device 1 has a constitution in which a first inspection probe 3 capable of contacting with a circuit board P which is aninspection object, and a conductor pattern on the circuit board P and capacitance between the conductor pattern and a reference electrode is measured by using the first inspection probe 3, to thereby enable to discriminate the quality of the circuit board P based on the measured capacitance. In the device, a second inspection probe 4 is provided additionally, and the first inspection probe 3 and the second inspection probe 4 are brought into contact respectively with two mutually adjoining conductive patterns, to measure capacitance between both conductor patterns, and short circuit inspection relative to both conductor patterns is executed based on the measurement result.
