A sampling device (3) which can capture various chlorinated organic compounds in both forms of particles and gases contained in a fluid at the same time and further can easily extract the captured chlorinated organic compounds is equipped with a sampling filter (7) being disposed in a holder (6) having a discharging path (12a). The sampling filter (7) comprises fibers and an inorganic binder for binding the fibers with one another and has a structure allowing a fluid to pass through the filter. A sample gas from a flue (25) flows into the holder (6) through a sampling tube (2) and a conduit (8), and various chlorinated organic compounds such as PCDDs and coplanar PCBs in both forms of particles and gases are captured and sampled while the sample gas passes through the sampling filter (7). The sample gas from which the chlorinated organic compounds have been removed is discharged out from the discharging path (12a).
