                            The present invention relates to a novel crystal form of a 3-(4-(benzyloxy)phenyl)hex-4-inoic acid derivative, a preparation method therefore and a pharmaceutical composition comprising same. A crystal form I of a compound of chemical formula 1, according to the present invention, exhibits more excellent physicochemical properties such as thermal stability, static electricity-inducing capability, compressibility, etc. compared to an amorphous form or a crystal form II, and thus is especially useful for preparation and long-term storage.
