Disclosed is a laminated balance filter which can be easily reduced in size and which can perform a predetermined impedance conversion between an input and an output. A first coil is constituted of a first linear electrode (121) and via electrodes (131 and 132). A first capacitor is constituted between a ground electrode (110) and a first capacitor electrode (111); a second capacitor is constituted between the ground electrode (110) and a second capacitor electrode (112); and a third capacitor is constituted between the ground electrode (110) and a third capacitor electrode (113). The first coil and the first capacitor constitute an LC parallel resonator. A second linear electrode (124) is arranged in parallel with the first linear electrode (121) so that second coils (122 and 123) and third coils (125 and 126) having loop faces normal to the loop faces of the first coil are constituted. The second capacitor and the third capacitor are connected between an equilibrium output terminal and the ground. |
