Objective The present invention intends to provide a small-sized impedance matching device with a small variation in quality and large-current tolerance. Means for Solution The above described intention of the present invention is achieved by an impedance matching device, which comprises:
a wiring portion comprising a conductor pattern for wiring, embedded inside or formed on the surface of first dielectric material, and
either one or both of:
an inductor portion comprising a conductor pattern for inductor, embedded inside or formed on the surface of said first dielectric material, or
a capacitor portion comprising at least one pair of conductor patterns for capacitor and second dielectric material with a dielectric constant larger than that of said first dielectric material, existing between the pair of conductor patterns for capacitor;
wherein the thicknesses of said conductor pattern for wiring and said conductor pattern for inductor are 20 am or more. |
