Abstract
An electronic component capable of preventing the occurrence of magnetic saturation due to a magnetic flux surrounding each coil conductor and a method of manufacturing the electronic component are provided. The electronic component includes a laminate formed by stacking unit layers, where each unit layer includes a first insulating layer, and a coil conductor and second insulating layer formed on the first insulating layer. Each second insulating layer has a Ni content greater than a Ni content of each first insulating layer. Portions of the first insulating layers have a Ni content lower than a Ni content of the second portions after the laminate is calcined.
Claims19
A method of manufacturing an electronic component, comprising the steps of:
- forming a laminate, said laminate comprising:
- a spiral coil including a plurality of connected coil conductors overlapping each other in a plain view in a stacking direction;
- and
- a plurality of continuously stacked first unit layers, each said first unit layer including a first insulating layer having a principal surface and overlaid with one of the coil conductors such that the one coil conductor entirely overlaps, and is adjacent to the principal surface when viewed in the stacking direction, and a second insulating layer having a greater Ni content than Ni content in the first insulating layer and provided adjacent to a portion of the principal surface of the first insulating layer other than where the one coil conductor is formed;
- and
- calcining the laminate.
