An active vibration and noise control device robust against outside disturbances, and an active vibration and noise control circuit are provided. An adaptive control circuit of this active vibration and noise control device has a cross-correlation value calculation unit which calculates the cross-correlation value of error signals, and a canceling output limiting unit which determines whether or not the cross-correlation value is less than a cross-correlation threshold value, and limits increases in the cancelling output if it is determined that the cross-correlation value is less than the cross-correlation threshold value.
