Dielectric filter and dielectric resonator

A dielectric filter, comprising:

• a cuboid laminated body comprising a plurality of dielectric layers laminated in a lamination direction, the cuboid laminated body having a first side surface and a second side surface perpendicular to a first direction orthogonal to the lamination direction;
• a first plate electrode and a second plate electrode disposed to be spaced apart from each other in the lamination direction on an inside of the laminated body;
• a first terminal and a second terminal that are disposed on the first side surface and the second side surface of the laminated body, respectively, and connected to the first plate electrode and the second plate electrode;
• a plurality of resonator portions disposed side by side in a second direction orthogonal to the lamination direction and the first direction in a region between the first plate electrode and the second plate electrode in the laminated body;
• and
• a plurality of capacitor portions disposed to face the plurality of resonator portions in the first direction, respectively, in a region between the plurality of resonator portions and the second terminal in the laminated body, wherein:
• each of the plurality of resonator portions comprises a plurality of resonant electrode elements laminated in the lamination direction, is connected to the first terminal, and is spaced apart from the second terminal;
• each of the plurality of capacitor portions comprises a plurality of capacitive electrode elements laminated in the lamination direction, connected to the second terminal, and provides a capacity between each of the capacitor portions and each of the resonator portions facing each of the capacitor portions in the first direction;
• a part of each of the plurality of resonant electrode elements facing the capacitive electrode element extends in a direction along the first direction;
• and
• at least one of the plurality of capacitive electrode elements extends in a direction intersecting with the first direction.
