Let <TEX>$H_1$</TEX> (<TEX>$\Delta$</TEX>, M) be the family of all 1-1 holomorphic mappings of the unit disk <TEX>$\Delta\; \subset\; C$</TEX> into a complex manifold M. Following the method of Royden, Hahn introduces a new pseudo-differential metric <TEX>$S_{M}$</TEX> on M. The present paper is to study the product property of the metric <TEX>$S_{M}$</TEX> when M is given by the product of two domains <TEX>$D_1$</TEX> and <TEX>$D_2$</TEX> in the complex plane C, thus investigating the hyperbolicity of the product domain <TEX>$D_1 \;\times\; D_2$</TEX> with respect to <TEX>$S_{M}$</TEX> metric.
