CHIP INDUCTOR AND METHOD FOR MANUFACTURING THE SAME

Title:

CHIP INDUCTOR AND METHOD FOR MANUFACTURING THE SAME

Document Type and Number:

WIPO Patent Application WO/1998/044520

Kind Code:

A1

Abstract:

The electrical characteristic of the chip inductor is improved by preventing the occurrence of short circuits among the linear conductor sections of the coil section of the inductor by appropriately insulating the conductor sections from each other and, at the same time, the mounting surface of the exterior section of the inductor is flattened so that the inductor can be mounted accurately on an object. The chip inductor is provided with a prism-like main body (1) made of an insulating material, electrode sections (6) positioned to both end sections of the main body (1), the coil section (5) which is connected to the electrode sections (6) and, at the same time, positioned on the outer periphery of the main body (1) between the electrode sections (6), and the exterior section (9) coating the coil section (5) with an insulating resin (8). The coil section (5) has the linear conductor sections (3) and groove sections (4) formed by grooving a conductor layer (2) formed on the surface of the main body (1). The internal spaces of the groove sections (4) are also filled up with the insulating resin (8).
