Disclosed are a temporal fixation method for use in the processing of an optical structural member and a curable composition suitable for use in the method. The curable composition comprises (A): a polyfunctional (meth)acrylate, (B): a monofunctional (meth)acrylate, (C): a photopolymerization initiator and (D): a polar solvent, and optionally (G) : a temperature-sensitive polymer and (H): a granular substance. The temporal fixation method comprises adhesively fixing a structural member temporarily using the curable composition, processing the temporarily fixed structural member, immersing the processed structural member in hot water of 30 to 90°C to cure the curable composition, and removing the cured composition.
