< Topic >Even under the vibration and impact, it is possible to make chlorine dioxide of the quantity discharge which is stabilized continuously the solid anti-bacterial medicine which is suited for carrying is offered. SolutionsThe anti-bacterial medicine which makes the anti-bacterial characteristic substance the porous mineral solid carrier support 1st (4) and the said anti-bacterial medicine is accommodated the sack body (2) and, 2nd 1st accommodates the sack body the sack body (3) and, being the sack entering anti-bacterial medicine which it has, 1st, it provides the micropore of smaller diameter than grain size of the mineral solid carrier extensively in the sack body, it provides the discharge hole (31) in order to discharge the aforementioned anti-bacterial characteristic substance in the atmosphere in the edge in the 2nd sack body. < Selective figure >Figure 1【課題】振動や衝撃の下でも、安定した量の二酸化塩素を継続的に放出させることが可能な、携帯に適した固形の抗菌剤を提供する。【解決手段】多孔性の無機質固形担体に抗菌性物質を担持させた抗菌剤(4)と、該抗菌剤を収容する第1の袋体(2)と、第1の袋体を収容する第2の袋体(3)と、を備えた袋入り抗菌剤であって、第1の袋体には、全面に無機質固形担体の粒径より小さな径の微細孔を設け、第2の袋体には、縁部に前記抗菌性物質を大気中に放出するための放出孔(31)を設ける。【選択図】図1
