To provide an alarm sound output device for reducing a possibility that a driver misunderstands that "intermittent sound is occurring when continuous sound is generated".SOLUTION: An alarm sound output ECU causes an alarm sound generating unit to generate an intermittent sound pattern having a predetermined output time Ton of an alarm sound and a stop time Toff of the alarm sound in the case where an intermittent sound condition is established when an index value having a correlation with a possibility of contact between a target and the own vehicle is equal to or less than a first threshold value and greater than a second threshold value which is smaller than the first threshold value; and when a continuous tone condition with an index value equal to or less than the second threshold is satisfied, the alarm sound output ECU causes the alarm sound generating unit to generate a continuous tone pattern that continues to generate an alarm tone without stopping the tone generation of the alarm tone. When the intermittent sound condition is satisfied, the alarm sound output ECU shortens a stop time by a predetermined interval as an index value decreases; and the alarm sound output ECU sets a stop time when the index value for establishing the intermittent sound condition is the smallest longer than the predetermined interval.SELECTED DRAWING: Figure 4

    【課題】ドライバーが「連続音が発生しているときに断続音が発生している」と誤認する可能性を低減させる警報音出力装置を提供する。【解決手段】警報音出力ECUは、物標と自車両との接触可能性と相関を有する指標値が第1閾値以下であり且つ第1閾値よりも小さい第2閾値よりも大きいときである断続音条件が成立した場合、警報音の所定の出力時間Ton及び警報音の停止時間Toffを有する断続音パターンを警報音発音部に発音させ、指標値が第2閾値以下である連続音条件が成立した場合、警報音の発音を停止させることなく警報音を発音させ続ける連続音パターンを警報音発音部に発音させる。警報音出力ECUは、断続音条件が成立している場合、指標値が小さくなるにつれて所定の間隔分ずつ停止時間を短くし、断続音条件を成立させる指標値が最も小さいときの停止時間を、所定の間隔よりも長く設定する。【選択図】図4
