We present a new methodology to derive positions of the Galactic center molecular clouds (MCs) along the line of sight, as an application study of the Galactic center diffuse X-rays (GCDX). We examined the Suzaku X-ray images and spectra of the GCDX near at MCs of Sgr B and Sgr C, and found that the GCDX can be divided into two parts: one suffers strong absorption by the MCs (N(sub H) > 10(exp 23) H cm(sup -2)) and the other does not (N(sub H) approximately6 x 10(exp 22) H cm(sup -2)). Assuming that the plasma of the GCDX is a sphere with a uniform volume emissivity around Sgr A(sup *), we quantitatively estimated the line-of-sight positions of the MCs from the flux ratios of the GCDX. We successfully drew a face-on view showing that the MCs near at Sgr B and Sgr C are respectively located at the near and the far sides with respect to Sgr A(sup *)
