Abstract
Provided is a resin material having non-ohmic properties which has favorable characteristics as a varistor and has a high degree of molding freedom and impact resistance. A resin materialcomprises: an insulating matrixmade of a first resin material; an island-form conductive dispersed phasemade of a conductive second resin material which is incompatible with the first resin material and is more wettable to a microvaristordescribed later than the first resin material is, wherein the island-form conductive dispersed phase is dispersed in an island form in the matrix and has a volume ratio of less than 16% in the whole resin material; and a microvaristorcomprising ceramic particles having non-ohmic properties, wherein the ceramic particles are dispersed in the matrixand electrically contacted with each other via the island-form conductive dispersed phase
