Abstract

PURPOSE:To reduce the effect of a stray capacity in a certain frequency range, by arranging conductor layers between dielectric layers and connecting inductance which is resonant with capacity between the conductor layers between the above mentioned conductor layers. CONSTITUTION:A conductor layer 2 of a first layer is provided between the conductor layer 1 of a second layer which indicates wiring or bonding pads and a substrate 3 and an inductance element 4 which is resonant with capacity Cs1 between the conductor layer 2 and the substrate 3 is connected to a space between the conductor layer 2 and the substrate 3. In such a case, impedance Z of an electric equivalent circuit is shown by an equation as per attached, provided that C12=Cs1=2Co and, since the above equation does not have a term which lessens an effect of inductance L such as an expression of L1-1/omega<2>C11 in comparison with the equation of impedance in the case where it is lacking in the conductor layer 2, its impedance Z can obtain the effect of inductance 1 to the maximum.
