PROBLEM TO BE SOLVED: To provide a noise filter that can remove noise in a normal mode by using a core made of a magnetic material and by suppressing magnetic saturation. SOLUTION: This normal mode noise filter 4 for power is constituted by fitting the core 2 made of the magnetic material to a power supply line 1 and, at the same time, passing a conductor 3 which becomes a secondary winding through the hole 2a of the core 2. After the conductor 3 is passed through the hole 2, both ends of the conductor 3 are connected to each other in a loop- like state (endless state). COPYRIGHT: (C)2004,JPO
