Title:
中空構造体の製造方法及び中空構造体製造用基板及び中空構造体製造装置
Document Type and Number:
Japanese Patent JP4869269
Kind Code:
B2
Abstract:
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.
