PROBLEM TO BE SOLVED: To provide an automatic stopping/restarting device of an internal combustion engine, and an automatic stopping/restarting method of the internal combustion engine, capable of properly releasing a drive inhibition state of a starter according to a rotating state of the internal combustion engine.SOLUTION: A drive inhibition state of a starter is released when a drive inhibition release determination time determined according to a time interval between a time when an initial reverse rotation crank signal is detected and a time when a second reverse rotation crank signal is detected, and a drive permission lower limit equivalent time corresponding to a starter drivable rotating speed lower limit value, passes before input of a third reverse rotation crank signal. 【課題】内燃機関の回転状態に応じて、スタータの駆動禁止状態を適切に解除することのできる内燃機関の自動停止再始動装置および内燃機関の自動停止再始動方法を得る。【解決手段】初回の逆回転クランク信号が検出された時刻と、２回目の逆回転クランク信号が検出された時刻との時間間隔と、スタータ駆動可能回転速度下限値に対応した駆動許可下限値相当時間とに応じて設定した駆動禁止解除判定時間が３回目の逆回転クランク信号が入力される前に経過すれば、スタータの駆動禁止状態を解除する。【選択図】図１
