Summary:To provide a small filter with good characteristics.SOLUTION: A filter 10 includes: a first resonator 11A having a first via electrode portion 20A; a second resonator 11B having a second via electrode portion 20B; and a third resonator 11C having a third via electrode portion 20C. The first via electrode portion 20A and the second via electrode portion 20B are offset from each other in a first direction X, and the third via electrode portion 20C is offset in a second direction Y which intersects in the first direction with respect to the first via electrode portion or the second via electrode portion.SELECTED DRAWING: Figure 1 【課題】特性の良好な小型のフィルタを提供する。【解決手段】フィルタ１０は、第１ビア電極部２０Ａを有する第１共振器１１Ａと、第２ビア電極部２０Ｂを有する第２共振器１１Ｂと、第３ビア電極部２０Ｃを有する第３共振器１１Ｃとを備え、第１ビア電極部２０Ａと第２ビア電極部２０Ｂとが第１方向Ｘにおいて互いにずらされており、第３ビア電極部２０Ｃが、第１ビア電極部又は第２ビア電極部に対して、第１方向に交差する第２方向Ｙにおいてずらされている。【選択図】図１
