A nonlinear resistive coating material (20) according to an embodiment comprises: a matrix resin (22) which comprises an epoxy resin that can be cured by the addition of a curing agent; ZnO-containing particles (21) which are dispersed and contained in the matrix resin (22) and which are made of a sintered material that comprises ZnO as a main component; and semiconductive surface-treated ZnO whiskers (10) which are dispersed and contained in the matrix resin (22) and which are surface-treated with a titanate coupling agent. Selon un mode de réalisation, une matière de revêtement résistante non linéaire (20) comprend : une résine matrice (22) qui comprend une résine époxy qui peut être durcie par l'addition d'un agent de durcissement ; des particules contenant ZnO (21) qui sont dispersées et contenues dans la résine matrice (22) et qui sont fabriquées d'une matière frittée qui comprend ZnO comme composant principal ; et des barbes de ZnO à surface traitée semi-conductrices (10) qui sont dispersées et contenues dans la résine matrice (22) et dont la surface est traitée par un agent de pontage titanate.
