Zusammenfassung:	To provide a magnetic heat pump device capable of achieving both a temperature difference and freezing capacity.SOLUTION: A design method of a magnetic heat pump device includes: a step S1 for calculating magnetic flux density BG1 in an air gap when a magnetic field generation part is opposed to a yoke with the air gap in between, at an interval LG1, calculates a parameter PA1, which is a product of the calculated magnetic flux density BG1 and the interval LG1, and calculates a parameter PA2, which is a geometric mean of the calculated parameter PA1 and magnetic flux density BG1; and a step S2 for acquiring an interval LG2, which is the interval LG1 when the parameter PA2 is maximum by repeating the step S1 while changing the interval LG1.SELECTED DRAWING: Figure 7 【課題】温度差と冷凍能力とを両立させることができる磁気ヒートポンプ装置を提供する。【解決手段】磁気ヒートポンプ装置の設計方法において、磁場発生部が空隙を挟んで間隔ＬＧ１でヨークと対向している時の空隙における磁束密度ＢＧ１を算出し、算出された磁束密度ＢＧ１と間隔ＬＧ１との積であるパラメータＰＡ１を算出し、算出されたパラメータＰＡ１と磁束密度ＢＧ１との相乗平均であるパラメータＰＡ２を算出するステップＳ１と、間隔ＬＧ１を変更しながらステップＳ１を繰り返すことにより、パラメータＰＡ２が最大となるときの間隔ＬＧ１である間隔ＬＧ２を取得するステップＳ２と、を有する。【選択図】図７
