A rotating electric machine driver and an electric power steering device are provided. The rotating electric machine driving apparatus includes a controller section (40) that obtains an electric current detection value (Ic) and generates instruction signals (UH, UL, VH, VL, WH, WL) for switching ON and OFF of switching elements (21-26) based on the electric current detection value (Ic). The rotating electric machine driving apparatus also includes an IC (50) that is provided with a signal amplifier (51) for outputting amplified signals (UHG, ULG, VHG, VLG, WHG, WLG), which are amplified instruction signals output from the controller section (40). When an abnormal state, in which one of an instruction signal (UH) and an amplified signal (UHG) amplifying the instruction signal (UH) is an ON instruction and the other one of the instruction signal and the amplified signal is an OFF instruction, continues for at least an abnormality determination time, an abnormality detector (55) determines an abnormality of the amplified signal (UHG), which realizes an appropriate detection of an abnormality of the amplified signal (UHG).
