The present invention is directed to a method for manufacturing a microstructure, the method comprising: (a) placing a viscous composition on a substrate and (b) applying negative pressure to the viscous composition to induce an extension of the viscous composition, thereby forming a microstructure, and a microstructure manufactured therefor. According to the present invention, a microstructure can be formed without performing a heat treatment by applying a negative pressure. Consequently, it is possible to mount on a microstructure various materials that are sensitive to heat and easily damaged or degenerated. According to the present invention, a microstructure can be manufactured in a non-contacting manner, that is, without being contacted with conventionally used another structure such as a mould or filler. This leads to overcome a loss caused during a process of separating a microstructure in contact or a cutting process involving a physical destruction after the completion of moulding a microstructure and limit on the production yield.
