Abstract

PURPOSE:To reduce heating power for a gas detecting element and to obtain a higher response speed by keeping a gas detecting element in a heat-insulated state. CONSTITUTION:A eutectic crystal of Au-Si is made and adhered to each other with adhesives in a N2 gas atmosphere between a metallic package 21 plated with Au and a gas detecting element 22 consisting of Si. Then an electrical connection between the gas detecting element 22 and the package 21 is performed by using a lead wire 24 made of Al wire. Then by putting the gas detecting element 22 in an atmosphere of a eutectic point or more of Au-Si, by raising it and by separating a junction between the gas detecting element 22 and the package 21, the gas detecting element 22 is holded in air with the Al lead wire 24. Next, by enclosing the circumference of the package 21 with a cylinder 27, resin such as polyimide or epoxy is inserted into the cylinder. After that, the resin 25, during 10-30min in air of about 60 deg.C, then during 30-60min in air of about 250 deg.C, is treated with heat and is cured.
