PROBLEM TO BE SOLVED: To provide an insulation inspecting device and method capable of rapidly and accurately inspecting insulation of a circuit board having a plurality of wiring patterns. SOLUTION: The insulation inspecting device 1 is used for inspecting the insulation of the circuit board 10 where a plurality of wiring patterns P are formed. The device 1 comprises a selecting means 2 for selecting one of the wiring patterns as a first inspection region (T1 shown in Fig.2A) and the other wiring patterns as a second inspection region (T2 shown in Fig.2A), a power supply means 3 connected to the second inspection region and adapted to apply a voltage to the second inspection regions so as to set a predetermined potential difference between the first and second inspection regions, a first current detecting means 4 connected to the first inspection region so as to detect a current flowing to the first inspection region, and a judging means 7 for comparing the current value detected by the first current detecting means with a predetermined reference value and judging that the circuit board is an acceptable one or a rejected one on the basis of the result of the comparison.
