る。従って、活性炭繊維の比表面積は７００〜２５００
ｍ2 ／ｇ、特に８００〜１５００ｍ2 ／ｇであることが
好ましい。In the present invention, when the specific surface area of the activated carbon fiber used is small, the deodorizing performance of the deodorizing antibacterial filter paper obtained is lowered, and when it is large, the pressure loss is large and the cost is high. Therefore, the specific surface area of the activated carbon fiber is 700 to 2500.
m 2 / g, it is particularly preferably 800~1500m 2 / g.

とするのが好ましい。なお、Ａｇ非含有ガラス繊維を用
いるときは、同上の理由で平均繊維径は０．５〜３μ
ｍ、特に０．５〜１．５μｍとするのが好ましい。If the Ag-containing glass fiber is too thin, the resulting deodorizing antibacterial filter paper will have a large pressure loss, and if it is too thick, the collection efficiency will decrease. Therefore, the average fiber diameter of the Ag-containing glass fibers is 0.5 to 3 μm, particularly 0.8 to 1.5 μm.
Is preferred. When Ag-free glass fibers are used, the average fiber diameter is 0.5 to 3 μm for the same reason as above.

が低下し、多いと高価となる。When the content of the activated carbon fiber is small, the deodorizing performance of the deodorizing antibacterial filter paper obtained is lowered, and when the content is large, the strength is lowered. If the content of the Ag-containing glass fiber is small, the antibacterial performance is deteriorated, and if the content is large, it becomes expensive.

The balance is preferably Ag-free glass fiber and solid binder (preferably fiber binder). Ag-free glass fiber is the cheapest of these components, is easy to disperse, and is 15% by weight or more,
It is particularly desirable to add 15 to 61% by weight. The solid binder content is preferably 0.04 to 20% by weight.
