Abstract
The disclosed sensor probe for detecting a gas component concentration such as an oxygen concentration has a specific gas introducing tube arranged in a gas probe tube, whose one end is faced to a gas sensor portion, and possessing a gas inlet hole for introducing a gas to be measured into the gas sensor portion through the gas introducing tube and a gas outlet hole for discharging the gas. Under such a construction, since a sufficient amount of a gas to be measured can be supplied effectively into the gas sensor portion even if a velocity of the gas is low, it is possible to maintain a high measuring accuracy.
