A fluid leakage detecting element comprises a heat generating resistive member and a temperature compensating resistive member disposed on a substrate. Each of the resistive members is prepared in the form of a paste of a metal which has a high temperature coefficient and a high thermal conductivity and whose melting point is higher than the baking temperature of the substrate. These resistive members are printed in thick film form on the substrate which is sufficiently electrical insulating and has a high thermal conductivity.
A fluid leakage detecting element comprising a substrate of electrical insulating material having a high thermal conductivity and having two opposing surfaces, one of which is adopted to be attached to a portion of a subject where a fluid contained in said subject may leak, a heat generating resistive member, said member being provided in thick film form on the other surface of said substrate and made of tungsten which has a high temperature coefficient, a high thermal conductivity and a melting point higher than the baking temperature of said substrate,...
