PROBLEM TO BE SOLVED: To provide a heat storage unit capable of improving heat storing and heat radiating capacities. SOLUTION: This heat storage unit 4 comprises a heat storage material exchanging the heat with a refrigerant, a heat storage container 41 for storing the heat storage material, and a first heat storage refrigerant passage RT1. The first heat storage refrigerant passage RT1 has a first gas inlet/outlet part 47 positioned at an upstream side of the refrigerant flow, and a first liquid inlet/outlet part 48 positioned at a downstream side of the refrigerant flow, and formed in the heat storage container 41 in a state of meandering while repeatedly intersecting with a specific plane. The first heat storage refrigerant passage RT1 is turned down so that the first liquid inlet/outlet part 48 is close to a first gas inlet/outlet part 47 in a projection view to the specific plane.
