MULTILAYER COIL COMPONENT AND METHOD FOR MANUFACTURING THE SAME

摘要

A closed magnetic path type multilayer coil component in which cracking or delamination hardly occurs between layers of different permeabilities. A first ceramic sheet (2) on which a conductor pattern (5) for coil is formed and a third ceramic sheet (4) having a permeability lower than that of the first ceramic sheet (2) are laminated, and the conductor patterns (5) for coil are interconnected electrically to constitute a coil being incorporated in a multilayer coil component (1). The third ceramic sheet (4) is sandwiched by the first ceramic sheets (2). A cavity (7) is formed in a major surface of the third ceramic sheet (4) and the first ceramic sheet (2) adjoining the third ceramic sheet (4) is in contact with the inner circumferential surface of the cavity (7).
