Abstract

PURPOSE:To restrain the bending of a lead wire after inserted by pushing and to reduce a correction process by providing in the lead wire a stopper which is wider than the internal diameter of the through hole wherein the lead wire is inserted in a cylindrical electronic part and by previously bending both of the ends of the lead wire. CONSTITUTION:A curved wire 14 which has a larger width (d) than the diameter D of the through hole 12 in a ferrite bead 11 for the length (b) (<=B) which is less than the length B of the ferrite bead 11 is formed at the center of a lead wire 13 of diameter d'. The lead wires 15, 16 of the both sides of the curved part 14 are bent to the direction A' with an angle alpha deg.. The lead wire 13 wherein the curved part 14 is coated with adhesives is inserted in the through hole 12 of the ferrite bead 11 from one end aperture 17 and the curved part 14 is pushed in for a temporal stop. In this case, the lead wires 15, 16 which are previously bent to the direction A' by the definite angle alpha deg. are made to just the direction of the axis of the beads core 11 and an inductance element which has no bent lead wire is obtained.
