A gas sensor mounting structure (10) is provided for mounting a gas sensor (1) that has a gas sensor element (2) and a sensor cover (3) covering the gas sensor element (2), in an exhaust manifold (5). The gas sensor (1) is mounted in the exhaust manifold (5) at such an angle with respect to the gas flow direction in the exhaust manifold (5) that makes it difficult for water present in the exhaust manifold (5) to come in contact with the gas sensor element (2). Also, the gas sensor (1) is mounted in the exhaust manifold (5) such that an axis (P) of the gas sensor (1) is not generally perpendicular to the exhaust manifold (5) at the mounting position. In addition, the gas sensor (1) is mounted immediately after a bend (R) in the exhaust manifold (5).
