We investigate self-gravitational collapse of magnetized molecular cloud cores and formation of the outflow. We employ a nested grid in order to resolve fine structures of protostar and outflow generation, of which size is as small as 1 AU, and to follow the whole structure of the molecular cloud core, of which radius reaches 0.1 - 1 pc, simultaneously. The nested grid allows us to follow the evolution of the cloud core with the high dynamic range of 105
