AbstractSuzaku X-ray observations of a young supernova remnant Cassiopeia A were carried out. The continuum emission is likely dominated by the non-thermal emission with a cut-off energy at approximately 3 keV. The peak of the non-thermal X-rays appears at the western part. The peak position of the TeV gamma-rays measured with HEGRA and MAGIC are also shifted at the western part with the 1-sigma confidence. Since the location of the X-ray continuum emission was known to be presumably identified with the reverse shock region, the possible keV-TeV correlations give a hint that the accelerated multi-TeV hadrons in Cassiopeia A are dominated by heavy elements in the reverse shock region.
