摘要：
A filtering device is disclosed that can be made compact and has wide-band band-pass characteristics. The filtering device includes a first filtering unit that is composed of a distributed constant circuit and is capable of eliminating a first frequency component or a second frequency component wherein the second frequency being higher than the first frequency, and a second filtering unit that attenuates components of frequencies lower than the first frequency or components of frequencies higher than the second frequency.
