Title:
LAMINATED COIL AND ANTENNA COIL
Document Type and Number:
Japanese Patent JP2005244768
Kind Code:
A
Abstract:

To provide a laminated coil and antenna coil capable of dealing with inductance error correction or customization.

The present invention relates to an antenna coil 1 comprising a laminated coil which is configured by laminating a plurality of coil sheets each having a coil pattern on at least one side of a substrate with a core inserting hole 7 bored thereon and by connecting coil terminals of upper and lower coil sheets with each other and becomes a Z-axis antenna coil, and a an XY antenna coil unit 8 including an X-axis antenna coil and a Y-axis antenna coil inserted into the core inserting hole of said laminated coil.
