摘要：
A dielectric filter is made of a dielectric material and includes a molded member of a pillar shape which has a hole formed from the top surface thereof toward the inside, an inner electrode formed so as to cover the inner circumferential surface of the hole; an outer electrode provided so as to cover the outer surface of the molded member except a prescribed region, and a coupling electrode provided at least in a portion of the prescribed region. An electrode area of a region of the inner electrode which faces against the coupling electrode is adjusted, thereby adjusting the coupling capacitance which is formed between the inner electrode and the coupling electrode.
