Abstract
A filter device includes a laminate body including dielectric layers, plate electrodes, resonators, shield conductors, and a capacitive electrode. The plate electrodes are spaced apart from each other in a lamination direction in the laminate body. The resonators are between the plate electrodes and extend in a first direction. The shield conductors are on side surfaces, respectively, that are orthogonal or substantially orthogonal to the first direction in the laminate body, and connected to the plate electrodes. The resonators are provided in a second direction orthogonal or substantially orthogonal to the lamination direction and the first direction in the laminate body. The resonators each include a first end connected to the shield conductor and a second end spaced apart from the shield conductor. The capacitive electrode couples the resonators.
