To obtain a device for inspecting paining patterns which is superior in maintainability and capable of performing general inspection on painting patterns.

In a device for inspecting painting patterns, it is determined whether the painting pattern of paint sprayed form a painting gun 2 is good or not. In this case, the device for inspecting painting patterns comprises an oscillation sensor 6 provided in the vicinity of the painting gun 2 to detect the oscillation characteristics of the painting gun 2, a data extracting means 9 to extract data on a specific frequency band by FFT analysis from the data on oscillation frequency detected by the oscillation sensor 6, and a determining means 9 to determine an failure at the time that the data on the frequency band obtained by the data extracting means 9 deviates from a previously inputted reference value.
