Claim of US Patent No. 10,798,815

1. A protection circuit module comprising:an insulating substrate including one surface, and another surface opposite to the one surface;
a first surge withstand chip resistor mounted on a pair of first pads formed on the one surface of the insulating substrate;
a second surge withstand chip resistor mounted on a pair of second pads formed on the other surface of the insulating substrate, and arranged at a position on the other surface of the insulating substrate overlapping the first surge withstand chip resistor in a plan view;
a first wiring coupled to one of the pair of first pads;
a second wiring coupled to one of the pair of second pads;
a third wiring coupling the other of the pair of first pads and the other of the pair of second pads to the same potential; and
a shield wiring, provided on an inner layer of the insulating substrate, and arranged in a region in which at least the one of the pair of first pads and the one of the pair of second pads oppose each other.
