The inlet port is connected to the inlet chamber, and conducts gas into the inlet chamber. The outlet port is connected to the outlet chamber, and conducts gas from the inlet chamber to the/outlet chamber through the filter sheet. The outlet port has an opening close to the gas passing portion of the filter sheet. The displacement restricting portion () restricts displacement of the gas passing portion toward the opening.
