PROBLEM TO BE SOLVED: To miniaturize a dielectric filter available at the high frequency band of 5 GHz or above. SOLUTION: In this dielectric filter, rectangular parallelepiped dielectric bodies 11 and 12 are joined with each other, an input and output electrodes 13 and 14 which are in contact with one side of one surface of each dielectric and whose three sides are surrounded by ground electrodes 15 and 16 are formed. Also, the earthing electrodes are formed on surfaces other than the surfaces and joint surfaces which are in contact with those electrodes. Then, dielectric resonators are connected to each other on the joint surfaces, and the connection is adjusted through conductor films 17 on the joint surfaces.
