A method for recycling a battery pack includes steps of: roasting the battery pack that houses a battery assembly that is in a charged condition, as it is, dismantling the roasted battery pack and separating the battery pack into unit cells and parts other than the unit cells, comminuting the unit cells obtained by separation, washing and screening the comminuted cells, dehydrating a slurry below a sieve after screening and recovering metals used for positive and negative electrodes, and recovering metal containing nickel by magnetically separating metal remaining on the sieve after screening, using a magnet.
