The gas sensor includes a sensor element, a heater for heating the sensor element, the heater having a roughly cylindrical shape, a housing into which the sensor element is inserted to be held therein, and a terminal unit disposed so as to cover a rear end portion of the heater on a rear end side of the housing. The terminal unit includes a pair of insulators, a pair of metal terminals each of which is located Inside a corresponding one of the pair of the insulators and in contact with a corresponding one of a pair of electrode pads provided on a surface of the rear end portion of the heater, and a pressing member pressing the pair of the insulators in a direction that the pair of the insulators approach each other. The pair of the insulators are located out of contact with each other. The rear end portion of the heater is contact-supported at at least three contact points by the terminal unit.
