<P>PROBLEM TO BE SOLVED: To provide a filter device with excellent productivity. Ž<P>SOLUTION: The filter device includes a conductor part 22a provided on an upper surface of a substrate 22, a metallic filter housing 21 mounted on the conductor part 22a, and an amplifier 26a mounted on a lower surface of the substrate 22, wherein: the filter housing 21 has a frame body 21b and a partition 21d provided in the frame body 21b and partitioning the frame body 21b into a plurality of spacers 21c; the partition 21b has one end connected to the frame body 21b and the other end connected to the substrate 22; and the amplifier 26a is mounted at a position of the substrate 22 which corresponds to the partition 21d. Consequently, the amplifier 26a, as well as other electronic components, can be easily produced using a general mounting machine, and the filter device with excellent productivity is achieved.
