Abstract
A laminated high frequency device includes a laminated body including plural magnetic sheets having relative permeabilities larger than 1, inductor patterns for forming plural inductors in the laminated body, and capacitor patterns forming a capacitor. The capacitor patterns are opposed to each other about another sheet of the laminated body. The inductors have large inductances without thickening of the magnetic sheet or thinning of the inductor patterns providing a large conductor loss. This arrangement reduces a size of the laminated high frequency device while providing isolation between the inductors.
