We report here the discovery of a new X-ray pulsator, AX J170006-4157, in the Galactic plane. The source was observed three times between 1994 and 1997 by the Advanced Satellite for Cosmology and Astrophysics. Significant pulsations with P=714.5±0.3 s were discovered from the third observation made between MJD 50,707.8926 and MJD 50,710.2199. The X-ray spectrum is described by a flat power-law function with a photon index of ≃0.7. Although the spectrum could also be fitted by thermal models, the temperature obtained was unphysically high. The hard spectrum suggests that the source is a neutron star binary pulsar similar to X Persei (4U 0352+309), but we cannot completely exclude the possibility that it is a white dwarf binary.
