Abstract

A multilayer electronic part having the shape of a substantially rectangular parallelopiped is constituted which has a multilayer body formed by superposing coil conductors and green sheets of a magnetic or nonmagnetic material. Terminal electrodes are formed respectively on both ends of the multilayer body along the direction of the magnetic flux generating when current is caused to flow through the coil conductors in the multilayer body. The terminal electrodes each has a conductive substrate formed within the area of the end of the multilayer body and consisting of a lamination body as a component of the multilayer body.

Dependent claims

A multilayer electronic structure in the shape of a substantially rectangular parallelopiped, comprising:

a first plurality of stacked sheets consisting of two coilless substantially planar end sheets and a second plurality of coil containing sheets wherein each of said second plurality of sheets includes a coil conductor and wherein said second plurality of stacked sheets form a coil with said two end sheets forming respective first and second terminal electrodes wherein the direction of stacking of said first plurality of sheets is along a direction of a magnetic flux generated when current is applied to flow through said coil conductors and wherein said stacked first plurality of sheets form a multilayer body.
