Abstract
The invention provides: a gas sensor device that is capable of removing a component adsorbed on a gas sensor by relatively simple means and easily restoring a signal baseline of the gas sensor to a constant state; and a method for removing a gas component. The gas sensor device according to an embodiment of the invention includes a gas sensor and cleaning means that contains a liquid for cleaning the gas sensor. The gas sensor includes a sensor main body that is capable of detecting a characteristic parameter of a component present in a gas phase or a liquid phase, and a sensitive membrane that is coated on a surface of the sensor main body and is durable against the liquid.
