We report the ASCA results of the supernova remnants (SNRs) and their candidates in the Galactic Center region. We found apparent X-ray emission from G359.1-0.5 and G0.9+0.1, and made marginal detection for G359.1+0.9, but found no significant X-ray from the other cataloged SNRs: G359.0-0.9, Sgr A East (G0.0+0.0), G0.3+0.0, Sgr D SNR (G1.0-0.1) (Green 1998). The emission from G359.1-0.5 is found to be thermal with multi temperature structures whereas that from G0.9+0.1 is quite hard, probably non-thermal. We discovered two new candidates of SNRs: G0.0-1.3 (AX J1751-29.6) and G0.56-0.01 (AX J1747.0-2828). The former, G0.0-1.3, shows the extended emission with a thin thermal plasma. The latter, G0.56-0.01, shows quite strong 6.7-keV line with the equivalent width of 2 keV, which resembles that of the Galactic Center plasma. We discuss the nature of those SNRs, relating with the origin of the Galactic Center hot plasma.
