PURPOSE:To improve the productivity of a gas sensor, by performing the steps from the molding of sensor main bodies to the connections to outer electrodes under the state many sensor main bodies are continuously arranged on electrode wires. CONSTITUTION:At first, each sensor main body 1 is molded in a shape, in which a pair of electrode wires are embedded, by press molding 1. At this time, the electrode wires penetrate through each sensor main body. A device, in which many sensor main bodies are continuously arranged on the electrode wires, is molded. At this time, at least one pair of the electrode wires can be used. Then, sintering 2 is performed with many sensor main bodies being continuously arranged on the electrode wires. After the sintering, the sensor main bodies are moved 3 with a transfer machine. The sensor main bodies are positioned with respect to at least two outer electrodes. The electrode wires are connected to the outer electrodes. At the same time or thereafter, the unnecessary parts of the electrode wires are cut. When strength is not sufficient in supporting the sensor main bodies with the electrode wires, the wire main bodies are contained in cavities, which are provided in heat insulating substrates. Flame coating 5 is applied on the surface of the substrate and on a part of the surface of each sensor main body. Thus the sensor main bodies are fixed in the cavities with flame coating films.
