Strong thermal X‐ray emission is observed along Galactic ridge (Galactic Ridge X‐ray Emission, GRXE, Koyama et al. 1989). Origin of hot component is not known, while cool one is made of supernovae(Kaneda et al. 1997). We propose a possible mechanism to explain the origin(Tanuma et al. 1999). We solved two‐dimensional resistive magnetohydrodynamics equations numerically to examine the magnetic reconnection triggered by a supernova. The magnetic reconnection heats X‐ray plasma in Galactic plane if it occurs in locally strong magnetic fields of 30 μ G. Heated plasma is confined by magnetic fields.
