Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a core capable of reducing eddy current loss, especially in a MnZn-based ferrite core.SOLUTION: A core is produced by laminating a plurality of magnetic cores, composed of Mn-Zn-based ferrite, in a predetermined direction. Following relations are satisfied: 1×10≤ ≤50, and 100≤1/d≤600, where is the specific resistance ( cm) of the magnetic core, and d is the average crystal grain diameter (cm). A relation D/ ≤10 is also satisfied, where D is the thickness (cm) of each magnetic core in a predetermined direction. With such a configuration, eddy current loss is reduced, and impedance of the laminated core can be enhanced.
