    • The present invention provides an air-permeable porous structural body that can be used for a vent plug or the like and imposes a low environmental load in waste treatment or the like after use, and also provides a vent plug using the porous structural body. Further, the invention provides an air-permeable porous structural body that can be molded by injection molding that has high productivity. The porous structural body has an overall structure entirely occupied by a structure composed of an infinite number of spherical or ellipsoidal cavities having a diameter of 1 μm to 100 μm. Holes are open in cavity walls and the cavity is linked to another cavity by the holes. The inside of the porous structural body is constituted by communicating open passages that pass in a meandering fashion between the inlet and outlet of the porous structural body and are composed of a plurality of cavities that are joined with each other in a chain configuration, and chain closed passages that are composed of one cavity or a plurality of cavities and connected to the communicating open passages. Further, 50 to 60% of the cavities per unit cube are cavities having a diameter of less than 10 μm.
    • 本发明提供一种透气性多孔结构体,其可以用于排气塞等,并且在使用后的废物处理等中施加低环境负荷,并且还使用多孔结构体提供排气塞。 此外,本发明提供一种透气性多孔结构体,其可以通过注塑成型而具有高生产率。 多孔结构体具有完全由由无数个直径为1μm至100μm的球形或椭圆形空腔构成的结构所占据的整体结构。 孔在空腔壁上开放,并且空腔通过孔连接到另一空腔。 多孔结构体的内部通过在多孔结构体的入口和出口之间以蜿蜒的方式连通的开放通道构成,并且由多个以链构造形式彼此连接的空腔构成,并且链条 闭合通道由一个空腔或多个空腔组成,并连接到连通的开放通道。 此外,每单位立方体的空腔的50-60%是直径小于10μm的空腔。
