A method for manufacturing a gas sensor includes: disposing a tubular holder and a tubular compact in a tubular metallic shell defining a through hole, the tubular holder defining a first insertion hole, and the tubular compact defining a second insertion hole; preparing a preliminary assembly in which a pin is inserted into the first insertion hole and the second insertion hole; pulling out the pin from the first insertion hole and the second insertion hole and inserting a sensor element into the first insertion hole and the second insertion hole such that a forward end of the pin will come into contact with an end of the sensor element; compressing the compact to thereby fix the sensor element inside of the metallic shell; welding a protection sleeve to the metallic shell to thereby form a semi-assembly; and combining the semi-assembly with another semi-assembly to thereby form the gas sensor.
