ものであった。(Operations and Effects of the Invention) In the conventional magnetic mttfi shown in Fig. 4, since it has a circular cross section, that is, a flat surface, there is a limit to the amount of resin material including ferrite that can be attached (therefore, there is also a limit to the improvement in magnetic force). ), it has low value as a magnetic fiber, and even bends.
It peeled off due to wear, that is, it had poor durability.
