PROBLEM TO BE SOLVED: To provide a reactor core which makes possible to ease the reduction in inductance in a current region over a rating current in a reactor with a silicon steel plate laminated core.SOLUTION: A reactor core comprises: a laminated core 1 formed by laminating silicon steel plates each having a thickness of 0.35 mm or less and a Si concentration within a range of 3.0-7.0 mass%; a dust core layer 2a provided in a center portion in a direction of lamination of the laminated core; and a dust core layer 2b provided at one or more than one point in a plane perpendicular to a direction of magnetization of the laminated core. Thus, it becomes possible to ease the reduction in inductance in a current region over a rating current in a reactor with a silicon steel plate laminated core. |
