A balanced-type dielectric filter for use in a high frequency circuit without requiring a converter. The balanced-type dielectric filter includes a dielectric block having an approximately rectangular parallelepiped shape, at least two inner conductors being disposed in parallel-with a longitudinal direction of the dielectric block and having the length approximately equal to 1/2 of a selected wavelength. Outer conductors are disposed on at least two outside surfaces of the dielectric block and are parallel to the inner conductors. Two pairs of connecting conductors connect the two inner conductors to input and output terminals located on the side surfaced of the dielectric block, the terminals being insulated from the outer conductors.
