Document Type and Number:
Japanese Patent JP2016100476
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a magnetic core excellent in productivity.SOLUTION: A magnetic core 12 includes an annular body formed by overlap bonding between both end parts of a plurality of laminar units disposed in an overlaid manner. Each of the plurality of laminar units is composed of an alloy ribbon laminate. The annular body includes: one or a plurality of overlap-bonded inner peripheral side laminar units at least including the innermost laminar unit; and an outer peripheral side laminar unit overlap-bonded on the outer peripheral side of the inner peripheral side laminar unit. The overlap length of the inner peripheral side laminar unit is longer than the overlap length of the outer peripheral side laminar unit.SELECTED DRAWING: Figure 3
