We report the Suzaku results of HESS J1614-518, which is the brightestextended TeV gamma-ray source discovered in the Galactic plane survey conductedusing the H.E.S.S. telescope. We discovered three X-ray objects in the field ofview of the X-ray Imaging Spectrometer (XIS), which were designated as SuzakuJ1614-5141 (src A), Suzaku J1614-5152 (src B), and Suzaku J1614-5148 (src C).Src A is an extended source located at the peak position of HESS J1614-518, andtherefore it is a plausible counterpart to HESS J1614-518. The X-ray flux inthe 2-10 keV band is 5e-13 erg/s/cm^2, which is an order of magnitude smallerthan the TeV flux. The photon index is 1.7, which is smaller than the canonicalvalue of synchrotron emissions from high-energy electrons found in somesupernova remnants. These findings present a challenge to models in which theorigin of the TeV emission is the inverse Compton scattering of the cosmicmicrowave background by accelerated electrons that emit X-rays via synchrotronemission. Src B is located at a relatively dim region in the TeV band image;however, its hydrogen column density is the same as that of src A. Therefore,src B may also be physically related to HESS J1614-518. Src C is a foregroundlate-type B star. We also discovered a soft extended X-ray emission near HESSJ1614-518.
