Zusammenfassung:	PURPOSE:To acquire high electrical conductivity and good magnetic properties by dispersing and forming ferrite in copper or copper group alloy. CONSTITUTION:For example, a ferrite powder of average diameter of 200mum is added by 2 weight ratio to 1 weight ratio of pure copper powder of average grain diameter of 150mum manufactured by water atomizing method, fully mixed to be pressed-formed to a rod-shape, and sintered in a nitrogen atmosphere. The formed rod has good magnetic properties and high electrical conductivity; the reason is that conductivity lowers only by a volume occupied by ferrite in conductive metal since crystalline lattice of copper is continuous with ferrite and therefore has extremely little distortion. As the magnetic material is provided with magnetic properties and electrical conductivity, it can be used for a relay part wherein a magnetic part and a conductive part are formed integrally.
