Abstract: In a resonant device, a first via electrode and a second via electrode connect a first plane electrode and a third plane electrode. A third via electrode and a fourth via electrode connect the first plane electrode and a second plane electrode. When the first plane electrode is seen in plan view in a normal direction of the first plane electrode, a first imaginary line connecting the first via electrode and the second via electrode intersects with a second imaginary line connecting the third via electrode and the fourth via electrode.

Abstract: A balance filter includes an unbalanced terminal, a first balanced terminal, a second balanced terminal, a ground terminal, an unbalanced-side coupling coil, a balanced-side coupling coil electromagnetically coupled to the unbalanced-side coupling coil, and an unbalanced-side capacitor. The unbalanced-side capacitor, the unbalanced-side coupling coil, and a portion of the balanced-side coupling coil define an LC parallel resonant circuit. A first end of the balanced-side coupling coil is a terminal having the same polarity as that of a first end of the unbalanced-side coupling coil. A second end of the unbalanced-side coupling coil is connected to the first end of the balanced-side coupling coil.

Abstract: A multilayer ceramic capacitor includes a multilayer body including dielectric layers and internal electrodes alternately laminated therein, and two end surfaces opposing each other in a length direction, and two side surfaces opposing each other in a width direction, and two external electrodes respectively on the two end surfaces of the multilayer body. At least one of two opposed main surfaces of the multilayer ceramic capacitor includes raised portions provided respectively on one side and another side with a middle portion of the main surface interposed therebetween. The raised portions are each raised to become thicker in the lamination direction from the middle portion toward an outer periphery of the main surface.

Abstract: A multilayer ceramic capacitor includes a multilayer body including dielectric layers and first and second inner electrodes that are laminated, and first and second outer electrodes. Each of the first inner electrodes includes a first opposing electrode portion and a first extending electrode portion. The first extending electrode portions at least positioned in a vicinity of the first and second principal surfaces in a lamination direction among the first inner electrodes include a first bent portion bent inward and a second bent portion bent outward in the lamination direction. A distance between vertices of the first and second bent portions in the lamination direction in the first inner electrodes positioned in the vicinity of the first and second principal surface in a lamination direction is larger than a distance in the first inner electrodes positioned in a central portion in the lamination direction.
