Abstract
To simplify the configuration of an oil state detection apparatus. The oil state detection apparatus 100 includes an oscillation circuit having a coil 1 and a capacitor 2 and a detection device configured to detect the oscillatory frequency of the oscillation circuit and having an oscillator 3 and a PLL circuit 4. One of the coil 1 or the capacitor 2 is immersed in oil OL. The oscillation circuit and the detection device are arranged on the same circuit board 20.
