Abstract
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.
