Title:
LAMINATED INDUCTOR
Document Type and Number:
Japanese Patent JP2004153067
Kind Code:
A
Abstract:
To provide a laminated inductor which can increase the area where magnetic flux can pass on a coil axial part, thereby improving a Q value and an inductance value.
Insulating layers and conductor patterns for a coil are laminated, and the conductor patterns for the coil each being sandwiched between insulating layers are connected spirally to form a coil in a laminate. Ends of the coil are connected to external terminals formed on the end faces of the laminate. Each conductor pattern for the coil has land patterns at its ends, and the land patterns are arranged at outer side than the inner circumference of the coil so that these land patterns are prevented from protruding to the coil axial part where the coil is wound.
