Document Type and Number:
Japanese Patent JP7342551
Kind Code:
B2
Abstract:
To provide a magnetic material core in which a magnetic permeability in a predetermined direction can be increased more than that in other directions, an inductor including the magnetic material core, and a method for manufacturing an inductor.SOLUTION: In an inductor, a magnetic material core 10 includes: a plurality of magnetic material particles 15 adjacent to each other at least in a first direction; and a covering body covering the plurality of magnetic material particles 15 individually, having insulation properties, and including a magnetic material. In the particle size of the magnetic particles, D10 and D90 are within ±30% of D50. The filling rate of the magnetic material particles 15 and the covering body is 60% or more.SELECTED DRAWING: Figure 3
