Abstract
A stepped portion is formed inside the inner-conductor holes arranged between both side surfaces of a dielectric block. The axis at an open end of the holes is made to be different from the axis at a short-circuited surface. The open ends of the inner-conductor holes are formed so as to be close to corresponding input-output electrodes.
