1. A nonlinear resistive coating material comprising:
a matrix resin made of an acrylic resin, an epoxy resin or a polyurethane resin, which is cured by heating;
particles dispersedly contained in the matrix resin and made of a sintered compact containing ZnO as a main component; and
semiconductive whiskers dispersedly contained in the matrix resin and made of ZnO subjected to titanate coupling surface modification treatment.
