The present invention concerns a sensor for voltammetric or amperometric measurement of the chlorite concentration (ClO2<->) in an solution. In order to provide a chlorite sensor which permits direct measurement of the chlorite concentration without taking samples, separating off accompanying substances or adding chemicals, and which has negligible cross-sensitivity in relation to typical accompanying substances of the chlorite, such as in particular chlorine dioxide (ClO2), chlorate (ClO3<->) and hypochlorite (OCl<->), it is proposed in accordance with the invention that the sensor has a working electrode of gold.
