Document Type and Number:
Japanese Patent JP6851204
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a magnetic core in which peeling, dropping or cracking of a flat power is less likely to occur with a ridge line part of an end face or a corner part to which the ridge line part is matched, defined as an origin, an inductor, and a manufacturing method thereof.SOLUTION: The present invention relates to a magnetic core consisting of a flat soft magnetic metal powder in 60 vol.% or more, a binder containing silicon nitride in 10 vol.% or more and 30 vol.% or less as a main component, and a compound magnetic substance including pores in 10 vol.% or more and 25 vol.% or less, being elastic and having a polygonal shape. A ridge line part and a corner part are rounded and an end of the soft magnetic metal powder in the rounded portion is folded.SELECTED DRAWING: Figure 2
