PROBLEM TO BE SOLVED: To provide a manufacturing method of a dielectric waveguide filter with which productivity is improved without need of a complicated process such as grooving, and high-accuracy filter characteristics is provided. SOLUTION: A conductor pattern having a window for coupling is formed on a composition surface of a plurality of dielectric substrates, the plurality of dielectric substrates are bonded, the bonded dielectric substrates are cut vertically to their surfaces to form a plurality of dielectric blocks each internally comprising a conductor pattern, an input/output conductor pattern is formed on one of cross sections, and a conductor film is formed over the relevant cross section other than a portion where the input/output conductor pattern is formed, and over the other three cross sections.
