Claims

[Claims for Utility Model Registration] A patterned electrode in which electrode portions constituting an inductance portion and a capacitance portion, respectively, are alternately formed on one of the opposing surfaces of a dielectric substrate; In the stripline filter, ground electrodes are formed on opposite surfaces of the dielectric substrate, and the dielectric substrate has an uneven cross section on the one opposite surface side, and the inductance portion is formed on the convex portion of the dielectric substrate. A stripline filter characterized in that an electrode portion and an electrode portion of the capacitance portion are formed in the recessed portions of the electrode portion.
