Abstract
A BPF comprises a first resonator and a second resonator connected in order between input/output terminals. The resonators each include an inductor conductor and a capacitor conductor formed in a laminate. The inductor conductors of both resonators have one open end and the other short-circuited end. The BPF further comprises a connection conductor for interconnecting the inductor conductors of the two resonators. This connection conductor connects the inductor conductor of the first resonator at a position close to the open end with the inductor conductor of the second resonator at a position close to the open end.
