(Problem to be solved by the invention) In the conventional fibrous filters mentioned above, Although tar components are collected in tobacco smoke, the collection effect is low, and aldehydes 1 such as acrolein, which are gas phase components in tobacco smoke, are not adsorbed and collected.
タール成分や有害な気相成分を吸着補集する方法として

There is one that is placed directly into a cylindrical paper body and has an acetate filter wrapped around the mouthpiece.
しかしながら、上述した活性炭を用いるフィルタにおい
ても気相成分はある程度補集できるもののタール成分を
も含む補集効果はいまだに満足しがたいものがあった。However, although the above-mentioned filter using activated carbon can collect gas phase components to some extent, the effect of collecting tar components is still unsatisfactory.

ばこの喫味を低下するという問題を生じる。Generally speaking, the effect of collecting tar components increases as the suction resistance value of the filter (the value expressed in terms of the height in the water necessary for 20 cc/filtration of air to pass through the filter) increases. If the suction resistance value is increased unnecessarily, a problem arises in that the smoking taste of the cigarette is deteriorated.

0, tar filtration speed is 8% and 7%, which are lower values than others, and acrolein is observed in the smoke passing through the filter in each sample, and the rate at which the other samples (within the scope of the present invention) pass through the filter is low. Acrolein is not detected in the smoke. In addition, the above sample No. 1 and sample No.
The reason why the tar filtration speed of 7 (marked with * in the table) is low can be judged to be due to the apparent low porosity (2.5% = less than 5%) and the small specific surface area, and the high suction resistance value is due to the low apparent porosity (2.5% = less than 5%). Similarly, the apparent appearance can be determined to be due to the low porosity.
