A first inner conductor, a second inner conductor, a first inner conductor, and a second inner conductor are disposed in the order mentioned from the top in the dielectric element. The first inner conductors are respectively led out to two opposing side surfaces of the dielectric element. A pair of the second inner conductors is respectively led out to two opposing side surfaces different from the two opposing side surfaces to which the first inner conductors are respectively led out. Terminal electrodes are respectively disposed on four side surfaces of the dielectric element for connection with these four inner conductors respectively.
