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 autocorrelation value calculation units which calculate an autocorrelation value of an error signal or of a target signal, which is a reference signal or a standard signal, and a canceling output limiting unit which determines whether or not an autocorrelation value is less than an autocorrelation threshold value, and limits increases in the cancelling output if it is determined that the autocorrelation value is less than the autocorrelation threshold value.
