されている。2. Description of the Related Art Conventionally, there is known a deodorizing filter in which a filter material having a dust removing function in a dust mask or an industrial filter is combined with a deodorizing agent for a malodorous gas such as ammonia, hydrogen sulfide and mercaptan. For the deodorant, powdered, particulate, fibrous, etc. activated carbon can be filled in a breathable container, or it can be fixed to a fiber surface such as a non-woven fabric via an adhesive,
Means for sandwiching and using two non-woven fabrics are well known. In addition to these, iron (II) ions, manganese (I
It is known that metal ions such as I) ions have an excellent deodorizing effect against malodorous gas. For example, Japanese Patent Laid-Open No. 1-290685 discloses ascorbic acid / oxypolybasic acid for manganese (II) ions. For supporting a composition in which activated carbon is bound on activated carbon, JP-A-3-21310
Japanese Unexamined Patent Publication 7 discloses a technique in which a reaction product of a metal such as Fe, Mn and Cr and an oxypolybasic acid is sandwiched between two nonwoven fabrics.

実用上必ずしも高くないから、脱臭が不十分になりがち
であるとか、それを避けるために多量の活性炭を必要と
するという問題がある。脱臭フィルタを使い捨ての防じ
んマスクに使用する場合、この問題は特に深刻である。When activated carbon is used as the deodorant combined with the dustproof filter, the saturated adsorption amount of the activated carbon to the malodorous gas and the adsorption amount per unit time are not necessarily high in practical use. Is apt to be insufficient, or a large amount of activated carbon is required to avoid it. This problem is particularly serious when the deodorizing filter is used in a disposable dust mask.

不織布等から脱落し易いという問題がある。Further, the method of storing powdery or granular activated carbon in a breathable container and using it tends to make the container bulky, and the activated carbon moves in the container to be unevenly distributed in one place, which causes aeration. On the other hand, there is a problem that it is difficult to maintain the activated carbon in a uniform thickness. The method of using this kind of activated carbon fixed to a non-woven fabric via an adhesive can make the deodorant into a thin sheet, which makes it easier to use depending on the application, but the activated carbon is covered with the adhesive and the deodorizing ability decreases. However, there is a problem that activated carbon easily falls off from the nonwoven fabric or the like.

However, fibrous activated carbon is generally fragile, and a sheet-shaped filter medium combined with the activated carbon easily loses its shape, so that it is difficult to use it as it is for a filter of a dust mask.

The technology of utilizing iron (II) ions and the like as the deodorant disclosed in JP-A-213107 can be expected to have a deodorizing effect superior to that of activated carbon, but this deodorant is formed into a sheet form so that it can be applied to a disposable dust mask.
