ELECTRONIC COMPONENT AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an electronic component in which the strength of a lamination body is improved while internal stress is mitigated.SOLUTION: An electronic component comprises: a laminate body 12 in which a plurality of insulator layers containing ferrite ceramic are stacked in a lamination direction; a spiral coil advancing in the lamination direction while moving around, to which a plurality of coil conductor layers 18a to 18h provided on the insulator layers and at least one or more veer hole conductors extending through the insulator layers in the lamination direction are connected. The first pore area rate in a side gap A1 sandwiched between the outer-peripheral side outer edge of an annular trajectory formed by the overlapping coil conductor layers 18a to 18h in a plan view from the lamination direction and the outer edge of the lamination body is 9.0% or more but 20.0% or less. A second pore area rate in a portion A2 sandwiched by two coil conductor layers in the lamination direction is 8.0% or less.SELECTED DRAWING: Figure 3A
