PROBLEM TO BE SOLVED: To provide an electrode-forming method that forms an electrode layer with satisfactory workability and high adhesion on a surface of a dielectric block to configure a dielectric filter or the like. SOLUTION: This method has a process where conductive paste is applied to an entire surface of a dielectric block 10 through dipping, a process where this conductive paste is tentatively baked at a temperature of 400-650 deg.C to form an electrode layer 12, a process where a trimming mask 20 is placed on the electrode layer 12 formed by the tentative baking, and abrasive grains are blown onto the electrode layer 12 from a nozzle 24, to grind the electrode layer 12 formed by the tentative baking into a prescribed shape in matching with a shape of an open window 22 of the trimming mask 20, and a process where the ground electrode layer 12 formed by the tentative baking is glost-fired at a temperature of 800-860 deg.C. |
