PROBLEM TO BE SOLVED: To provide a means of preventing a circuit improper operation by suppressing the generation of a displacement current charging and discharging parasitic capacitance due to a dv/dt surge. SOLUTION: A first lead frame 3a is disposed so as to correspond to a low-potential reference circuit section LV and a second lead frame 3b is disposed so as to correspond to a high-potential reference circuit section HV, whereby a part of an insulating substrate 2, positioned below the low-potential reference circuit section LV is brought into a state where the part is held at the same potential between the low-potential reference circuit section LV and a first lead frame 3a and a part of the insulating substrate 2, positioned below the high-potential reference circuit section HV is brought into a state where the part is held at the same potential between the high-potential reference circuit section HV and the second lead frame 3b.
