The distributed constant type noise filter is made of a belt-shaped current carrying conductor (3) having first and second lead wires (1, 2) for input and output purposes connected near both ends of said current carrying conductor (3) and of a belt-shaped ground conductor (5) having a ground lead wire (4) connected near one end of said ground conductor (5). Said current carrying and ground conductors (3, 5) are wound in a tubular form with sandwiched dielectric sheets therebetween. The noise filter is characterized in that said first lead wire (1) of said current carrying conductor (3) and said ground lead wire (4) of said ground conductor (5) are shifted by about 1/4 to 3/4 turn with respect to each other, and said second lead wire (2) of said current carrying conductor (3) is positioned substantially on a symmetry axis (14) including the center of the winding and said first lead wire (1) and/or said ground lead wire (4). |
