Common mode choke coil of the conductor/insulator stacked type that uses a high machinability substrate and benzocyclobutene as the insulator

摘要

An electronic component comprises an insulator substrate (11), a layered member composed of a plurality of insulator resin layers (12a-12f) and a plurality of conductor pattern layers (13a-13f) alternately stacked on the insulator substrate to form a first conductor line and a second conductor line each of which comprises at least one conductor layer, first and second external electrode terminal portions connected to opposite ends of the first conductor line and covering first and second areas of side surfaces of said layered member and the insulator substrate, respectively, and a third external electrode terminal portion connected to one end of the second conductor line and covering a third area of the side surfaces of the layered member and the insulator substrate. The second conductor lines have magnetic and electrocapacitive coupling with respect to the first conductor line.
