Abstract:
1. An inorganic-particle-dispersed sputtering target for use in a magnetron sputtering device comprising a DC power source, the sputtering target in which inorganic particles are dispersed in a metal base material essentially consisting of Co, wherein the inorganic particles have an electric resistivity of 1×10 1 Ω·m or less and the volume ratio of the inorganic particles in the target is 50% or less, and said inorganic particles having a dimension and a shape in which a value obtained by dividing the surface area (unit: μm 2 ) of inorganic particles dispersed in the sputtering target by the volume (unit: μm 3 ) of the inorganic particles is 0.6 or more (unit 1/μm).
