PROBLEM TO BE SOLVED: To provide a novel crystalline form of gemcitabine-[phenyl-(benzoxy-L-alaninyl)]-(S)-phosphate. A crystalline form of gemcitabine-[phenyl-(benzoxy-L-alaninyl)]-(S)-phosphate, which is Form I. When measured using Cu radiation having a Kα2/Kα1 ratio of 0.5, 2θ of 5.0±0.2, 6.7±0.2, 8.0±0.2, 11.3± Said crystalline form, characterized in that it has an XRPD pattern with at least two peaks selected from 0.2, 20.2±0.2 and 21.4±0.2.
