Abstract
A dielectric filter having a dielectric block disposed on a mount board. The dielectric block includes inner conductor holes having open ends on the front surface of the dielectric block. Input/output electrodes are disposed on the undersurface of the dielectric block. Each of the input/output electrodes extends from the boundary between a side surface and the undersurface of the dielectric block to the boundary between the front surface and the undersurface of the dielectric block. An outer conductor includes undersurface electrode corner portions and an undersurface electrode main portion. Each of the undersurface electrode corner portions is disposed at a corner formed by the front surface and one of the side surfaces of the dielectric block.
