A laminated balance filter includes a first capacitor electrode and a ground electrode that are disposed opposite to each other to define a capacitor at an unbalanced side. An unbalanced side coil is provided in a dielectric layer. Three balanced side coils are provided in three dielectric layers. The three balanced side coils preferably have a substantially helical shape and are wound in the same winding directions. The coil located in the center of the three balanced side coils is disposed near the unbalanced side coil so as to be electromagnetic-field-coupled to the unbalanced side coil.
