    • There is provided a method of manufacturing a hollow structural member suitable for precisely manufacturing a hollow structural member whose pitch space of the hollows is below 30 μm. The method of manufacturing a hollow structural member of this invention is to encapsulate, by using a gas-permeable material in part of a material that constitutes the substrate (5) for manufacturing the hollow structural member, a high-pressure gas by injection in advance, under high-pressure conditions, into the gas-permeable material; to form a plastic deformation film (10) on a surface under reduced-pressure conditions; and to expand and draw the plastic deformation film (10), while preventing the plastic deformation material from entering the recesses (5b), by discharging the high-pressure gas that is encapsulated in the gas-permeable material into each of the recesses (5b), whereby the hollow structural member is manufactured.
    • 提供了一种制造中空结构件的方法,该中空结构件适于精密制造中空结构件,其中空间的间距小于30μm。 制造本发明的中空结构件的方法是通过在构成用于制造中空结构件的基板(5)的材料的一部分中使用透气材料来封装预先注入的高压气体 在高压条件下进入透气材料; 在减压条件下在表面上形成塑性变形膜(10); 并且通过将封装在透气材料中的高压气体排出到每个凹部5b(5b)中,同时防止塑性变形材料进入凹部(5b)而膨胀并拉伸塑性变形膜(10) ),由此制造中空结构构件。
