摘要： PROBLEM TO BE SOLVED: To provide a composite soft magnetic material having favorable DC superposition characteristics and high specific resistance, and a production method therefor.SOLUTION: An inorganic insulative powder 3 and a coated powder obtained by coating with a silicone resin 2 a soft magnetic powder 1 that is coated with an insulative film 4 are uniformly mixed, and the mixture is molded and fired. By uniformly mixing the inorganic insulative powder and the coated powder obtained by coating with the silicone resin the soft magnetic powder that is coated with the insulative film 4, rupture of the insulative film caused by the inorganic insulative material in molding pressed powder is prevented. By uniformly dispersing the inorganic insulative material while high specific resistance is maintained, the gap between molded soft magnetic powder particles is uniformly maintained. As a result, a composite soft magnetic material is provided having high specific resistance and favorable DC superposition characteristics.

摘要： PROBLEM TO BE SOLVED: To provide a magnetic material allowing the flexibility of shapes and relative permeability to be enhanced and its manufacturing method.
SOLUTION: This is a magnetic material provided with magnetic metal powder 31A, 31B, 31C, and 32 in resins 33 and 34, and the magnetic metal powder 31A, 31B, 31C, and 32 are formed into a flat shape. The lengthwise directions x and x' of the respective adjacent magnetic metal powder 31A, 31A', 31B, 31B', 31C, 31C', 32, and 32' are oriented approximately parallel to each other. The lengthwise directions x and x' of the magnetic metal powder 31A, 31B, 31C, and 32 are oriented approximately parallel to the line of magnetic force Y of a magnetic field. Even though the magnetic material is made of the magnetic metal powder 31A, 31B, 31C, and 32, the permeability can be improved. Since the magnetic metal powder 31A, 31B, 31C, and 32 are arranged in the resin 33 and 34, the flexibility of shapes of the magnetic material can be improved.
