We report our 110 ks Chandra observation of the supernova remnant 0104-72.3 in the Small Magellanic Cloud. The X-ray morphology shows two prominent lobes in NW and SE surrounded by soft faint emission. While previous X-ray observations suggested a point-like source in the SE region coincident with a candidate Be star, no such source is detected in our Chandra observation. The X-ray spectra of the lobes show overabundant Fe, broadly consistent with shocked stellar ejecta of Type Ia SN. This work was supported in parts by SAO under Chandra grant GO8-9059X.
