The physical process of the magnetic reconnection associated with the emerging flux is discussed. The parameter dependence of the process is studied. A numerical simulation is performed with the two dimensional magnetohydrodynamic code. A two temperature layered plasma similar to the solar photosphere/chromosphere and corona in magnetostatic equilibrium is considered. The results show that magnetic flux in the photosphere emerges by magnetic buoyancy instability as rising loops. It is found that the magnetic reconnection is more violent, when the resistivity is smaller, or when the specific heat ratio gamma is smaller. It is also found that there are four types of jet like flow associated with the reconnection: hot jet along the magnetic field lines, slingshot jet, simple island ejection,and surge like cool jet.
