Abstract
A ladder filter includes an insulation substrate and a plurality of pattern electrodes provided on one major surface of the insulation substrate. A piezoelectric resonator which is a first series resonator, a piezoelectric resonator which is a first parallel resonator, a piezoelectric resonator which is a second parallel resonator and a piezoelectric resonator which is a second series resonator are arranged on the substrate in this order. External electrodes of these piezoelectric resonators are respectively bonded to the lands via a conductive bonding agent and are connected to pattern electrodes, respectively.
