There is provided a gas sensor that includes a sensor element, a heater that comprises an electrode, a housing that holds the sensor element therein, an insulator assembly that surrounds a part of the heater and is constituted of a plurality of insulators, an electric terminal member that is located between the one of the plurality of the insulators and the electrode of the heater, a cover that covers the insulator assembly, a holder for holding the insulator assembly, and an elastic member that is located between the holder and the cover to generate elastic force which is applied at least to the one of the plurality of the insulators to pinch the heater between the one and another one of the plurality of the insulators via the holder so as to bring the electric terminal member into constant electric contact with the electrode of the heater.
