Abstract
A gas sensor includes a sensor element that includes a gas inlet through which a measurement target gas is introduced into the sensor element and a protective cover that contains a substance having a capability of decomposing ammonia. The protective cover has a gas-contact surface area within a range of 450 mmto 1145 mm, the gas-contact surface area being a sum of a surface area of a portion facing the inlet-side gas flow path and a surface area of a portion facing an in-element-chamber flow path of the sensor element chamber that is a shortest flow path for the measurement target gas from the element-chamber inlet to the gas inlet.
