ABSTRACT:
A noise suppressor capable of achieving reduction in size and weight of devices is provided. The noise suppressor is a circuit for suppressing normal mode noise which is transmitted through a first current-carrying wire and a second current-carrying wire, and causes a potential difference between the current-carrying wires, and the noise suppressor includes a magnetic core including one magnetic material portion and another magnetic material portion magnetically coupled to the one magnetic material portion, and forming two magnetic loops so as to share the one magnetic material portion between them, an inductor including a first coil and a second coil which are wound around the one magnetic material portion so as to have an odd number of turns in total, and are inserted into and connected to the first current-carrying wire in series; and a capacitor having one end connected to a connecting point between the first coil and the second coil and the other end connected to the second current-carrying wire.
