A rush current to an oxygen sensor is restricted to very small to secure the high reliability of oxygen sensor.A non-inverting input of an amplifier 30 is grounded. A resistor 31 is connected between an inverting input and an output of said amplifier 30. A limited electric current type oxygen sensor 34 is connected between said inverting input of said amplifier and a reference power supply 33.
