Abstract

The present invention provides a noise filter capable of realizing electromagnetic interference tolerance in a desired frequency range in a high frequency band. The present invention relates to a noise filter 4 and a sensor circuit 1 using the noise filter. The noise filter is inserted into a path electrically connecting the output terminals 2a, 2b of a sensor 2 to a detector circuit 5 that detects the output signal of the sensor 2. Its feature is comprising: the first and second inductance elements 7,8 located on the sensor 2 side as at least one impedance element; and at least one capacitance element 9 connected between the impedance element and the detector circuit 5.
