Abstract
Provided is a method for manufacturing a gas sensor capable of securing airtightness without a chip in a sensor element. The method includes a step of obtaining an assembled body constituting the gas sensor, including steps of: causing one end of the sensor element to abut to a positioning member for positioning the sensor element; applying a force Fto the annularly-mounted members including a powder compact annularly mounted to the sensor element under a state that the sensor element is positioned and thereby compressing the powder compact so as to fix the sensor element inside of the tubular body, applying a force Flarger than the force Fto the annularly-mounted members under a state that the sensor element is not positioned and thereby further compressing the powder compact, so as to hermetically seal inside of the tubular body.
