MANUFACTURING METHOD FOR ELECTRONIC COMPONENT

摘要

An electronic component includes a multilayer body formed by laminating an insulator substrate and a plurality of insulator layers, a coil including coil conductors provided on the insulator substrate, and an internal magnetic path penetrating the insulator substrate. A manufacturing method for the electronic component includes: forming the coil conductors and a sacrificial conductor at the same time on a mother insulator substrate, which is the assemblage of a plurality of the insulator substrates; laminating insulator sheets, which are to be the corresponding insulator layers mentioned above, on the mother insulator substrate so as to cover the coil conductors; and exposing the sacrifice conductor by removing part of the insulator sheets.

1. A manufacturing method for an electronic component including a multilayer body formed by laminating an insulator substrate and an insulator layer, a coil including a coil conductor provided on the insulator substrate, and an internal magnetic path penetrating the insulator substrate, the method comprising:
forming the coil conductor and a sacrificial conductor provided at a portion where an internal magnetic path of the insulator substrate is to be formed, at the same time on the insulator substrate; laminating the insulator layer on the insulator substrate so as to cover the coil conductor and the sacrifice conductor; and exposing the sacrificial conductor by removing part of the insulator layer laminated on the insulator substrate.
