  We present results of the Galactic supernova remnant (SNR) G355.6-0.0
observed with Suzaku. We resolved the diffuse emission detected with ASCA into
two objects, G355.6-0.0 and a point-like source, Suzaku J173530-3236. The X-ray
emission from G355.6-0.0 exhibits a center-filled morphology within the radio
shell. The X-ray spectrum is well represented by a thin thermal plasma model
with enhanced metal abundances. The spatial and spectral properties imply that
G355.6-0.0 is a member of the mixed-morphology SNRs. The NH value of ~ 6 x
10^{22} cm^{-2} supports that G355.6-0.0 is a distant SNR. Suzaku J173530-3236
exhibits a hard X-ray spectrum with a strong Fe emission line, similar to those
of cataclysmic variables. The NH value of ~ 3 x 10^{22} cm^{-2} is smaller than
that of G355.6-0.0, and hence Suzaku J173530-3236 is located at the near side
of G355.6-0.0.
