An LC parallel resonator includes a plurality of dielectric layers stacked on top of one another, a capacitor electrode, and an inductor electrode. The inductor electrode defines a loop including a connection point, as a start point, connected to the capacitor electrode. The inductor electrode includes a first line electrode, first via electrodes, and second via electrodes. The first line electrode extends in a direction perpendicular or substantially perpendicular to a stacking direction of the dielectric layers. The first via electrodes arranged in parallel or substantially in parallel with one another extend in the stacking direction of the dielectric layers, and connect the capacitor electrode to the first line electrode. The second via electrodes arranged in parallel or substantially in parallel with one another extend in the stacking direction of the dielectric layers and are connected to the first line electrode.
