Statistical studies of satellite observations have revealed the plasmoid evolution and the characteristics of them (Ieda, 1998, Machida, 2004). In our previous studies (Ugai et al., 2005; Ugai and Zheng, 2005), the plasmoid evolutions in the no-sheared magnetic field were studied using MagnetoHydroDynamic(MHD) simulations. However, the magnetic field in the solar corona and the geo-magnetotail are usually sheared. Then, we studies plasmoid evolution in sheared magnetic field using MHD simulation on the basis of spontaneous fast reconnection model, and analyze the characteristics of plasmoid. These results are compared with actual satellite observations.
