We present the results of three-dimensional MHD simulation of solar emerging flux. The simulation was carried out on the Earth Simulator with high resolution. We found that filamentary structure spontaneously arose in the emerging flux due to the magnetic Rayleigh-Taylor instability. Furthermore, filamentary current sheets were formed in the emerging flux, and magnetic reconnection occurred between the emerging flux and the pre-existing coronal field in a spatially intermittent way. These naturally explain the intermittent nature of coronal heating and the origin of fine structure in flares and jets.
