PROBLEM TO BE SOLVED: To provide a load distribution device and a load distribution method with which it is possible to reduce a response time and the processing load of a processing server while reducing the quantity of signals to collect information on the processing server.SOLUTION: A load distribution device 100 comprises: an information storage unit 120 (storage unit) for storing the CPU limit value (load limit value) of a processing server at the own base; a load information acquisition unit 110 for acquiring the CPU use rate (load information) of the processing server at the own base; a signal count calculation unit 130 for calculating the number of own base return signals S for allocating signals to be allocated to processing servers at other bases to the processing server at the own base within an extent that does not exceeds the CPU limit value on the basis of the maximum value of the acquired CPU use rate and the load fluctuation rate A of the processing server at the own base; and an allocation unit 140 for allocating the calculated number of own base return signals S from the other bases to the processing server at the own base.SELECTED DRAWING: Figure 1 【課題】処理サーバの情報を収集するための信号量を減らしつつ、応答時間と処理サーバの処理負荷を減らすことができる負荷分散装置および負荷分散方法を提供する。【解決手段】負荷分散装置１００は、自拠点の処理サーバのＣＰＵ限界値（負荷制限値）を記憶する情報格納部１２０（記憶部）と、自拠点の処理サーバのＣＰＵ使用率（負荷情報）を取得する負荷情報取得部１１０と、取得したＣＰＵ使用率の最大値と自拠点の処理サーバの負荷変動率Ａとに基づいて、ＣＰＵ限界値を超えない範囲で、他拠点の処理サーバに振り分けるべき信号を自拠点の処理サーバに振り分ける自拠点戻信号数Ｓを算出する信号数算出部１３０と、算出した自拠点戻信号数Ｓ分を、他拠点から自拠点の処理サーバに振り分ける振分部１４０と、を備える。【選択図】図１
