Abstract
An oxygen concentration sensor for electrically sensing oxygen concentration in a gaseous body, including an oxygen pump element, a sensor cell element whose operating voltage is relatively low, and a heater element for heating the sensor cell element. For the electrical connection, the oxygen concentration sensor is provided with a first connector having terminals connected to the oxygen pump element and the heater element whose operating voltages are relatively high, and a second connector discretely from the first connector and having only terminals connected to the sensor cell element so that leakage of the relatively high operating voltage to the terminals of the sensor cell element is prevented.
