With the Suzaku satellite, we observed an unidentified TeV gamma-ray sourceHESS J1741$-$302 and its surroundings. No diffuse or point-like X-ray sourcesare detected from the bright southern emission peak of HESS J1741$-$302. Fromits neighborhood, we found a new intermediate polar candidate at the positionof $(\alpha, \delta)_{\rm J2000.0} = (\timeform{17h40m35.6s},\timeform{-30D14m16s})$, which is designated as Suzaku J174035.6$-$301416. Thespectrum of Suzaku J174035.6$-$301416 exhibits emission lines at the energy of6.4, 6.7 and 7.0 keV, which can be assigned as the K$\alpha$ lines fromneutral, He-like and H-like iron, respectively. A coherent pulsation is foundat a period of 432.1 $\pm$ 0.1 s. The pulse profile is quasi-sinusoidal in thehard X-ray band (4$-$8 keV), but is more complicated in the soft X-ray band(1$-$3 keV). The moderate period of pulsation, the energy flux, and thepresence of the iron K$\alpha$ lines indicate that Suzaku J174035.6$-$301416 islikely an intermediate polar, a subclass of magnetized white dwarf binaries(cataclysmic variables).  Based on these discoveries, we give some implications on the origin of GCDXand brief comments on HESS J1741$-$302 and PSR B1737$-$30.
