Dielectric filter, transmission-reception sharing unit, and communication device

A dielectric filter comprising:

• a dielectric plate;
• a first electrode formed on a first main surface of the dielectric plate, parts of the electrode being electrodeless;
• a second electrode formed on a second main surface of the dielectric plate, parts of the electrode opposed to the electrodeless parts of a first main surface being electrodeless;
• wherein the electrodeless parts on the dielectric plate form dielectric resonators;
• wherein the dielectric resonators are aligned in a line;
• and,
• wherein an angle formed by the line and at least one of linearly-formed coupling members coupled with a specified one of the dielectric resonators is of a specified number of degrees other than 90 degrees.
