  We report on new Suzaku and XMM-Newton results concerning HESS J1614-518,
which is one of the brightest extended TeV gamma-ray sources and has two
regions with intense gamma-ray emission. We newly observed the south and center
regions of HESS J1614-518 with Suzaku, since the north region, including the
position of the 1st brightest peak of the TeV gamma-ray emission, has already
been observed. No X-ray counterpart was found at the position of the 2nd
brightest peak of the TeV gamma-ray emission; we estimated the upper limit of
the X-ray flux to be 1.6 \times 10^{-13} erg cm^{-2} s^{-1} in the 2-10 keV
band. The soft X-ray source Suzaku J1614-5152, which was found at the edge of
the field of view in a previous observation, was also detected at the middle of
HESS J1614-518. Analyzing the XMM-Newton archival data, we revealed that Suzaku
J1614-5152 consists of multiple point sources. The X-ray spectrum of the
brightest point source, XMMU J161406.0-515225, can be described by a power-law
model with a photon index of Gamma = 5.2^{+0.6}_{-0.5}, or a blackbody model
with temperature kT = 0.38^{+0.04}_{-0.04} keV. In the blackbody model, the
hydrogen-equivalent column density is almost the same as that of the hard
extended X-ray emission, Suzaku J1614-5141, which was found at the 1st peak
position. If true, XMMU J161406.0-515225 may be physically related to Suzaku
J1614-5141 and HESS J1614-518.
