The present invention prevents the property of a laminated filter from diverging from a desired property while suppressing an increase in the size of the laminated filter and an increase in the manufacturing cost thereof. A laminated filter (1) according to an embodiment of the present invention is provided with an LC parallel resonator and an LC series resonator. The LC parallel resonator includes a first inductor (L1) and a first capacitor (C1). The LC series resonator includes a second inductor (L2) and a second capacitor (C2). A plurality of dielectric layers include a first inductor layer, a second inductor layer and a capacitor layer. In the first inductor layer, the first inductor (L1) is formed. In the second inductor layer, the second inductor (L2) is formed. In the capacitor layer, the first capacitor (C1) and the second capacitor (C2) are formed. The capacitor layer is disposed between the first inductor layer and the second inductor layer.
