PURPOSE: An electrothermal integrator and an audio frequency band-pass filter are provided to apply a thermally-isolated electrothermal structure that is manufactured by a micromachining technology. CONSTITUTION: An electrothermal structure(100) filters a high frequency electric signal. An input signal processing circuit(10) converts an electric signal to be filtered into a proper input signal and inputs the same to the electrothermal structure(100). An output signal processing circuit(20) converts an electric signal output from the electrothermal structure(100) into a proper output signal and outputs the same. A bias circuit(30) applies a bias voltage to the above parts, respectively. The electrothermal structure(100) includes a heater(110) and a sensor(120). A heat is generated in the heater(110) by the electric signal inputted to the electrothermal structure(100) from the input signal processing circuit(10) and the heat causes resistance of the sensor(120) to be changed. A voltage change of the sensor is generated. The output signal processing circuit(20) converts the changed voltage into a proper electric signal and outputs the same to the outside.
