We report on Suzaku results of the two distinct regions in the Galacticsupernova remnant G348.5+0.1: extended thermal X-rays ("soft diffuse") at thenortheast region and non-thermal X-rays (CXOU J171419.8-383023) at thenorthwest region. The X-ray spectrum of the soft diffuse is fitted with neitheran ionization equilibrium nor a non-equilibrium (ionizing) plasma model,leaving saw-teeth residuals in the 1.5-3 keV energy band. The residualstructures can be produced when free electrons are recombined to the K-shellsof highly ionized Mg and Si ions. In fact, the X-ray spectrum is nicely fittedwith a recombination-dominant plasma model. We propose a scenario that theplasma in nearly full ionized state at high temperature quickly changed to arecombining phase due to selective cooling of electrons to a lower temperatureof ~0.5 keV. The spectrum of CXOU J171419.8-383023 is well explained by asimple power-law model with a photon index of 1.9, nearly equal to the typicalvalue of pulsar wind nebulae. Since the distance is estimated to be the same asthat of the soft diffuse, we infer that both the soft diffuse and CXOUJ171419.8-383023 are associated with the same object, SNR G348.5+0.1.
