The vinylidene fluoride resin having improved crystallization properties relatively high molecular weight difference Tm2-Tc of the resin to the original melting point Tm2 and the crystallization temperature Tc is represented by at 32 ° C. or less, vinylidene fluoride resin the compositions plasticizers and obtained by mixing together the good solvent, the hollow fiber membrane to melt extrusion, cooling from subsequent outer surface is introduced into the cooling medium, and solidified, extraction of the plasticizer, be subjected to stretching Accordingly, the production of crystal orientation part and a crystal unoriented vinylidene fluoride mixed is observed in the portion resin hollow fiber porous membrane by X-ray diffraction method. The obtained porous membrane of vinylidene fluoride resin has a moderate micropore size and distribution, the mechanical strength typified by and tensile strength and elongation at break better, it is useful as a precision water filtration membrane.
