Title:
LAMINATED COIL COMPONENT
Document Type and Number:
WIPO Patent Application WO/2013/035516
Kind Code:
A1
Abstract:
In a laminated coil component (1), the particle diameter of coil conductors (4, 5) after sintering, is 10μm to 22μm.
By setting the particle diameter of the coil conductors (4, 5) after sintering to be 10μm or greater, the surface roughness can be reduced to the extent that a sufficient Q value can be acquired with high frequency. Further, by setting the particle diameter of the coil conductors (4, 5) after sintering to be 22μm or less, dramatic melting of the metal in the coil conductors (4, 5) during sintering can be minimized. Therefore, a high Q value can be obtained while maintaining high quality.
