Summary:An electrochemical gas sensor with a stacked arrangement of electrodes and nonwoven layers arranged in parallel, comprising at least one measuring electrode (3) and at least one counterelectrode (5). A porous membrane (8) that is permeable to air is in contact with the stacked arrangement of electrodes and nonwoven layers arranged in parallel at least on one side, at least one layer of a hydrophilic nonwoven (7) is located between the electrodes. The porous membrane (8) that is permeable to air and the hydrophilic nonwoven (7) extend into a separate equalization volume (9), which is filled with electrolyte at least partially and is located at least partially in one plane with the electrodes. The separate equalization volume (9) surrounds the electrode arrangement at least partially in this plane, and the porous membrane (8) that is permeable to air is exposed to ambient pressure at least in partial areas. Such sensors are characterized by a flat shape, high insensitivity to shocks, independence from the posit
