The variable resistance nonvolatile storage device reduces variations in a resistance value of a variable resistance element (100) in the low resistance state, performs stable operations, and includes an LR write circuit (500) (i) applying a voltage to a memory cell (102) so that a resistance state of the variable resistance element included in the memory cell is changed from high to low, and (ii) including a first driving circuit (510) and a second driving circuit (520) which apply voltages to the memory cell and which have connected output terminals. When applying a voltage to the memory cell, the first driving circuit supplies a first current, and the second driving circuit (i) supplies a second current when a voltage at the output terminal of the first driving circuit is higher than a reference voltage VREF, and (ii) is in a high impedance state when the voltage is lower than the VREF.
