PROBLEM TO BE SOLVED: To stabilize a position of a conducting path relative to a ferrite core without using any other member.SOLUTION: A noise filter includes a ferrite core 10 surrounding a wire (conducting path) 40S and a case 20 accommodating the ferrite core 10. The case 20 includes: a peripheral wall part 22 surrounding the ferrite core 10; and a plurality of elastic holding pieces 24 which protrude radially inwardly from a plurality of positions at intervals in a circumferential direction of the peripheral wall part 22 and of which the protruding ends (elastic abutting parts 28) are elastically abutted to an outer circumference of the wire 40S. Even if an outer diameter of the wire 40S surrounded by the ferrite core 10 is different, an elastic bending amount of the plurality of elastic holding pieces 24 is changed in accordance with the outer diameter, such that the wire 40S is held in the state where the position relative to the ferrite core 10 is stabilized. |
