To obtain a downsized dielectric filter suitable for a laminating structure, a dielectric filter is configured with use of a dielectric waveguide formed of a conductor pattern and vias in a laminating direction within a multilayer dielectric substrate, two strip lines formed in a planar direction of the multilayer dielectric substrate, and two strip line-waveguide converters each configured to perform transmission line conversion between the dielectric waveguide and each strip line. In this manner, it is possible to provide a dielectric filter for which an area to be occupied in the planar direction of the multilayer dielectric substrate is suppressed.
