Abstract
A micro-shape transcription method has preparing a mold having a transcription face on which a concavo-convex pattern is formed, pressing the transcription face against a base material softened by heating, then forcibly separating the mold from the base material to transcribe a reverse pattern of the concavo-convex pattern to the surface of the base material, wherein when assuming a temperature for pressing the mold against the base material as T(° C.), a temperature for separating the mold from the base material as T(° C.), thermal expansion coefficients of the mold and the base material as αand α, and the maximum distance between the transcription center of the transcription face and the concavo-convex pattern as d (mm), the following relations (1) and (2):T≧T  (1)|α−α|·()·≦4×10  (2)are simultaneously satisfied.
