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.
