Abstract
PURPOSE:To obtain a gas detection element having high mass productivity, by fixing a pair of a square pillars made of heat-resisting porcelain and having electrodes on the upper and lower faces leaving a prescribed space and connecting both electrodes with a platinum wire and then, covering this platinum wire with a gas sensitive body. CONSTITUTION:A pair of square pillars provided with electrodes 2, 2' on both faces of alumina substrates 1, 1' is melt-stuck at the cental part by glass containing an organic binder leaving a prescribed space. Next, both electrodes of the upper face of the substrate and that of the lower face of the substrate are connected with the wires 3, 3' respectively. Pasty substance whichis sensitive to combustible gas is dropped to connecting part of these wires 3, 3' and the substrate and is calcined after drying. Voltage is applied between the electrodes 2 using eithter of the two platinum wire, for example, the wire 3 as a heater and the space between the electrodes 2, 2' is made the resistance variation takeout electrode of a gas sensitive material 5 by operating said part as a combustible gas detection element.
