Reduction of arousal induction effect can be suppressed.Solution: the sleepiness detecting unit 110 for detecting the sleepiness level indicative of the degree of sleepiness of the user u, and when the sleepiness level detected by the sleepiness detecting unit 110 satisfies a predetermined standard, the awakening induction part 300 which drives the awakening induction part 300 which induces the awakening of the user u, and when the predetermined time elapses after it has been driven A control section 120 for stopping the wakefulness induction section 300 is provided.Diagram【課題】覚醒誘導効果の低下を抑制できる。【解決手段】ユーザＵの眠気度合いを示す眠気レベルを検出する眠気検出部１１０と、眠気検出部１１０が検出した眠気レベルが所定の基準を満たす場合に、ユーザＵの覚醒を誘導する覚醒誘導部３００を駆動させ、駆動させてから所定時間が経過したときに覚醒誘導部３００を停止させる制御部１２０と、を備える。【選択図】図２
