Abstract: We propose a new reconnection mechanism "chaotic reconnection". A basic mechanism of the chaotic reconnection is examined by means of numerical simulations of collision between two vortex-current filaments. The term "reconnection" means a reconnection of the filaments. We conclude that thle chaotic process works to enhance the reconnection rate of the filaments. We shall propose a similar chaotic process as a candidate for the mechanism of the fast magnetic reconnection.
