Abstract
In a method for manufacturing a gas sensor, a casing for holding a sensor element and a protective cover are connected to each other so that a distal end portion of the sensor element is covered with the protective cover. A first gas chamber, a sensor element chamber, and a second gas chamber into which gas is introduced from the outside are formed between the protective cover and the casing. In the gas introduction portion including the first gas chamber, the sensor element chamber, and the second gas chamber, there is no joint portion formed by welding.
