PROBLEM TO BE SOLVED: To easily manufacture a porous film by which a transfer of a high resolution can be performed at a high speed by an ink transfer printer. SOLUTION: In order to form through holes S', a common salt which is a water-soluble material is sintered, and a shape memory resin 20 is infiltrated into the gaps formed by the common salt. By solidifying the shape memory resin 20 and dissolving the common salt with water, an initial film 20a is formed. By pressing the initial film 20a under a shape imparting temperataure, a film having through holes, which close at a normal temperature and are openable at the glass transition temperature or higher, can be easily manufactured. |
