begin{HTML} X-ray emission from a cataloged radio supernova remnant (SNR), G344.7-0.1, was observed in the ASCA Galactic Plane Survey. The X-ray image showed extended emission with a diameter of 6'–8'. The X-ray spectrum exhibited emission lines from He-like Si, S, Ar, and Ca, which indicates that the X-rays have a thermal plasma origin. The spectrum was represented by a thin thermal plasma model with a temperature of 0.7-0.8keV. The model fit showed that S and Ca are overabundant relative to the solar values. In addition to the emission lines from highly ionized atoms, an emission line at an energy of ∼ 6.4 keV was found. This line is attributable to a K transition line from low-ionized iron. The strong Fe-Ka line may suggest the existence of an Fe-rich plasma.
