Line filter, image forming apparatus, and electronic device

摘要

A line filter (100) includes a flat plate-shaped cable (20) and a flat core (10). A through hole (11) having a shape corresponding to the cable (20) is formed in the core (10). The cable (20) includes: a first penetrating portion (21) which enters the through hole (11) in the core (10) from an inlet (12) of the through hole (11) and is passed through an outlet (13) of the through hole (11); a second penetrating portion (22) which enters the through hole (11) in the core (10) from the inlet (12) of the through hole (11) and is passed through the outlet (13) of the through hole (11); and a first connecting portion (30) which connects the first penetrating portion (21) on a side of the outlet (13) of the through hole (11) to the second penetrating portion (22) on a side of the inlet (12) of the through hole (11) not through the through hole (11). When viewed in a normal direction of a main surface of the core (10), the second penetrating portion (22) overlaps with the first penetrating portion (21) at least partially.
