Abstract
An electronic component includes a main body composed of an insulator, a coating film covering the main body, a circuit element located inside the main body, and outer electrodes. The insulator contains a metal magnetic powder. The coating film is composed of a resin and a cationic element contained in the insulator.
Claims12
An electronic component comprising:
- a main body including an element assembly composed of a metal magnetic powder and an insulating resin, and an inner conductor located inside the element assembly;
- a coating film covering the element assembly;
- and
- outer electrodes connected to the inner conductor,
- wherein the coating film contains:
- a reaction product of a resin and a cationic element constituting the metal magnetic powder or a reaction product of a resin and a cation of the cationic element constituting the metal magnetic powder, and
- wherein the cationic element has an ionization tendency larger than that of a metal contained in the inner conductor.
