To surely notify a user of an abnormality occurring in a noise filter circuit of an electronic apparatus.
A multifunction machine 1 has a noise filter circuit 20, each current detecting mechanism 41, 42, and a display part 8a. The noise filter circuit 20 includes an AC line 3 that has a live line 11 and a neutral line 12 in order to supply power to a multifunction-machine body 2, and each Y capacitor C3, C4 interposed between each line of the AC line 3 and a ground. Each current detecting mechanism 41, 42 is respectively provided on each line 51, 52 between each Y capacitor C3, C4 and the ground so as to detect a current flowing between each Y capacitor C3, C4 and the ground. The display part 8a is connected to each current detecting mechanism 41, 42 so as to display the state that each current detecting mechanism 41, 42 does not detect a current while supplying power to the multifunction-machine body 2 when it occurs.
