1. A sensor apparatus comprising:
a sensor element;
a cover member disposed above the sensor element, which defines a first flow passage, a second flow passage and a third flow passage,
wherein the first flow passage takes in a gas sample, the second flow passage introduces the gas sample onto the sensor element, the third flow passage sends the gas sample to an outside of the sensor apparatus, and the first flow passage, the second flow passage and the third flow passage communicate with one another;

an apparatus for maintaining a liquid membrane on the sensor element, comprising:
a liquid supply unit configured to supply a liquid onto the sensor element and to form a liquid membrane, and
a liquid discharge unit configured to discharge the liquid in the liquid membrane,
wherein the liquid supply unit includes a first container which accommodates the liquid, and the liquid discharge unit includes a space in which the liquid discharged from the liquid membrane is collected and a first member having one end arranged in the space and another end arranged on the sensor element,
wherein the liquid discharge unit is configured to discharge the liquid in the liquid membrane by the first member and the first member is made from a non-woven fabric; and

an airflow generation apparatus which generates a flow of air flowing from the first flow passage, passing through the second flow passage, and flowing to the third flow passage;
wherein
the sensor element is arranged between the liquid supply unit and the liquid discharge unit, and
part of the first member of the liquid discharge unit is arranged in the third flow passage.
