PROBLEM TO BE SOLVED: To improve the productivity and economy by applying an eternal force to a supercooled crystalline epoxy resin while kept at a specified temperature to grow crystal nuclei and then granulating the resin. SOLUTION: An external force is applied to a supercooled crystalline epoxy resin having a mesogen skeleton of the formula [wherein X is -N=N-, -CH=CH-, -C-CO-, -CH=C(CH3 )-, -CH=CH(CN)-, -C≡C-, -CH=CH-CO-, or a single bond; and R7 and R8 are each a 1-6C linear or cyclic alkyl, H or a halogen] while kept in a temperature range from the glass transition temperature to the melting point to grow crystal nuclei, and the resin is then ground.
