ABSTRACT:
A ladder-type filter includes a base substrate serving as a support substrate. A resonator group is supported on the surface of the base substrate. The resonator group includes first, second, third and fourth resonators, all of which have an electrode formed on each of a first side and a second side of their respective piezoelectric substrates. The first to fourth resonators are stacked and mechanically bonded to form layers and electrically connected in a ladder shape by conductive bonding agents providing mechanical and electrical connection.
