PROBLEM TO BE SOLVED: To provide an antibacterial agent storage body which can smoothly discharge chlorine dioxide when an antimicrobial agent is carried and used.SOLUTION: An antibacterial agent storage body 1 comprises: a particulate antibacterial agent containing an antibacterial substance and a storage body 3 storing the antibacterial agent. The storage body 3 is formed into an approximately flat shape to have a pair of surfaces, and the inside of the storage body 3 is provided with a scattering prevention film 2 which prevents scattering of the antibacterial agent and allows permeation of the antibacterial substance. The storage body 3 is formed with diffusion holes 4 which expose the scattering prevention film 2 outside. At least one of the storage body 3 and scattering prevention film 2 is formed with a large number of projections 9 which form a clearance between facing surfaces of the storage body 3 and scattering prevention film 2.COPYRIGHT: (C)2015,JPO&INPIT【課題】抗菌剤を携帯して使用する場合において、二酸化塩素の放出を円滑に行うことのできる抗菌剤収容体を提供することを課題とする。【解決手段】抗菌性物質を含む粒子状の抗菌剤と、該抗菌剤を収容する収容体3とを備えた抗菌剤収容体1であって、前記収容体が、略扁平状に形成されて一対の面を有するとともに、内部に、前記抗菌剤の飛散を防止するとともに前記抗菌性物質の透過を許容する飛散防止膜2を備え、かつ、前記収容体に、前記飛散防止膜を外部へ露出させる拡散孔4が形成され、前記収容体若しくは前記飛散防止膜の少なくとも一方には、前記収容体と前記飛散防止膜との対向面間に隙間を形成する多数の突起9が形成されていることを特徴とする。【選択図】図3
