A gas sensor includes a sensor element, and a protection cover accommodating a part of the sensor element that includes one end in a longitudinal direction. When a length in the longitudinal direction from the one end of the sensor element to a middle point of a gas inflow hole of the protection cover is represented as La, and a length index between the sensor element and a circle determined by an inner surface of the protection cover is represented as Lb, a ratio La/Lb is 0.9 or more, and, when sum of respective surface areas of two principal surfaces and two side surfaces of the sensor element corresponding to a portion of the length La is represented as S, and a volume of space in the protection cover existing corresponding to the portion of the length La is represented as V, a ratio S/V is 0.15 mm−1 or more.
