An electrochemical gas sensor with a plurality of electrodes is provided with an electrolyte, with a gas-permeable membrane ( 1 ), with a gas-permeable and conductive carrier layer ( 2 ) applied to the membrane ( 1 ) and with at least one measuring electrode ( 3 ) applied to the carrier layer ( 2 ). The measuring electrode ( 3 ) is of a punctiform design and the electrochemical potential difference of the reaction between the carrier layer ( 2 ) and the measuring electrode ( 3 ) is at least 20 mV, can be manufactured in a compact form and makes possible an especially low power consumption for measured gases in the percentage range.
