A capacitor of a certain LC resonator, among multiple LC resonators in a band-pass filter, is arranged at a side of one main surface in a stacking direction of a multilayer body of the band-pass filter and the capacitors of the remaining LC resonators are arranged at a side of the other main surface in the stacking direction of the multilayer body. One of a pair of capacitor electrodes of the capacitor of the certain LC resonator is grounded. The one capacitor electrode that is grounded covers at least the plurality of LC resonators, as viewed from the stacking direction of the multilayer body.
