Title:
LAYERED COIL COMPONENT AND COIL MODULE
Document Type and Number:
WIPO Patent Application WO/2015/156051
Kind Code:
A1
Abstract:
A layered body (120) is obtained by layering a plurality of magnetic sheets. Coil conductors (B01, A01) are embedded in the layered body (120) in a manner such that a winding axis forms a coil (CIL00) extending in the layering direction. When viewed from the layering direction, the coil conductors (B01, A01) form a ring. A void (AG01) is formed in a region surrounded by the inner-circumferential edge of the ring formed by the coil conductors (B01, A01), when viewed from the layering direction. The coil conductors (B01, A01) sandwich the void (AG01) in the layering direction, and are surrounded by the magnetic bodies so as not to be exposed to the void (AG01).
