The shield conductors are connected to the plate electrodes. The resonators are disposed inside the stack body side by side in the X-axis direction. A first end of each of the resonators is connected to the shield conductor, and a second end thereof is separated from the shield conductor. The first end of each of the resonators is formed with a cutout.
