PROBLEM TO BE SOLVED: To provide a laminated dielectric filter which can be easily miniaturized. SOLUTION: Any one of a balanced-to-unbalanced transformer and a filter element is configured by a first substrate laminate and the other is configured by separating it into a second and third substrate laminates, and the first substrate laminate is vertically sandwiched. Since the filter is configures so that the elements are separated, miniaturization of the elements can be attained by the reduction of a substrate area. COPYRIGHT: (C)2006,JPO&NCIPI
