To provide a water jacket capable of preventing leakage of a refrigerant even when an external force is applied, and capable of being made compact and high in quality.SOLUTION: A water jacket WJ for cooling an inverter module IM includes bases 1A to 1D each having a thin plate shape. Each of the bases 1A to 1D includes a refrigerant inflow part 12 into which the refrigerant flows; a refrigerant flow passage 11 which communicates with the refrigerant inflow part 12 and branches inside each of the bases 1A to 1D; and a refrigerant outflow part 13 which communicates with the refrigerant flow passage 11 and from which the refrigerant flows out.SELECTED DRAWING: Figure 3 【課題】外力が掛かっても冷媒の漏れを防止することができ、コンパクト化且つ高品質化が可能なウォータージャケットを提供する。【解決手段】インバータモジュールＩＭを冷却するウォータージャケットＷＪは、薄板形状を有する基台１Ａ～１Ｄを備える。基台１Ａ～１Ｄは、冷媒が流入する冷媒流入部１２と、冷媒流入部１２に連通し、基台１Ａ～１Ｄの内部で枝分かれした冷媒流動路１１と、冷媒流動路１１に連通し、冷媒が流出する冷媒流出部１３と、を備える。【選択図】図３
