The eclipsing low-mass X-ray binary AX J1745.6-2901 was observed with Suzakuin its outburst phase. Combining the Chandra observation made 1.5 month earlierthan Suzaku, we determined the orbital period to be 30063.76+/-0.14 s. We founddeep flux dips prior to the eclipse phase of orbit. The X-ray spectrum of thepersistent phase is described with a combination of a direct and a scattered-inby dust emissions. During the eclipse, the X-ray spectrum becomes only the dustscattering (scattered-in) component. The optical depth of the dust-scatteringis ~10.5 at 1 keV. The direct component is composed of a blackbody likely fromthe neutron star surface and a disk-blackbody. No power-law component is foundin the hard energy band up to 30 keV. A clear edge at ~7.1 keV in the deep dipspectrum indicates that the major portion of Fe in the absorber is neutral orat low ionization state. We discovered four narrow absorption lines near theK-shell transition energies of Fe XXV, Fe XXVI, and Ni XXVII. The absorptionline features are well explained by the solar abundance gas in a bulk motion of~10^3 km/s.
