In this case, the oscillation output of an oscillator OSC is applied to the power source ES as a fine signal. Detection signals of the current transformers T1 and T2, on the other hand, are rectified synchronously by the output Vi of the oscillator OSC. Consequently, the measuring instruments M1 and M2 detects only effective components of the output Vi, which are indicated or displayed and also outputted to the outside as a buzzer signal. Thus, the occurrence of grounding is detected as to the cubicles 11 and 12 individually.

Then, since the impurity concentration is on the decrease at a given gradient between the dot line 9 and the Pn junction 4a, the Pn junctions 5a of the second diffused region 3a is formed in the distribution of a given gradient in the surface as well as in the depth direction. Accordingly, the impurity concentration in the surface 8 in the neighborhood of the Pn junction 5a decreases; therefore, the reverse withstand voltage of this Pn junction 5a increases relatively.
