This invention relates to a stable hyaluronidase liquid formulation comprising a hyaluronidase and a stabilizer for hyaluronidase. In particular, the hyaluronidase has a purity of 95% or more and the specific activity of 70,000 IU/mg or more, and the stabilizer for hyaluronidase contains a buffering agent in order to provide pH of 4.0 to 6.0； 0.001 to 0.5 v/v % of a non-ionic surfactant； and 0.1 to 5 mM of a chelating agent or MgCl2. The liquid formulation has advantages in that it stably maintains its activity for a long period of time and may be easily administered than the conventional formulations.
