PROBLEM TO BE SOLVED: To make a device satisfying a standard of the Electrical Appliances and Material Safety Act satisfy a standard of the CISPR15 by using a relatively small size filter device.SOLUTION: A composite choke coil 31 has inductance as a common mode choke coil, and inductance as a normal mode choke coil. The inductance as the common mode choke coil is, for example, 30 mH, and the inductance as the normal mode choke coil is, for example, 600 μH. The capacitance of an across-the-line capacitor 34 is, for example, 0.1 μF. The inductances of the normal mode choke coils 32 and 33 are, for example, 390 μH, respectively. |
