PROBLEM TO BE SOLVED: To provide a high-performance reflection type band-pass filter for a UWB which has superior coupling properties for a transmission line such as a slot line and can meet standards of an FCC. SOLUTION: Disclosed is the reflection type band-pass filter for super-wideband radio information communication which is provided, on the surface of a dielectric substrate, with a center conductor and side conductors provided on both sides of the center conductor across nonconductor portions for securing a predetermined inter-conductor distance. The reflection type band-pass filter is characterized in that the center conductor width or/and inter-conductor distance are unevenly distributed all over the length direction of the center conductor.
