To solve a problem in which it is necessary to increase a heat storage material packing rate and to secure a clearance of a flow channel of a heat medium transferring heat to the heat storage material in changing solid-liquid phases, in order to improve heat storage density per volume.
This heat storage device comprises a heat storage container provided with a heat medium inlet 5 and a heat medium outlet 6, the laminated heat storage material 1, and a wire netting 2, and the wire netting 2 and the laminated heat storage material 1 are successively stacked on a partitioning plate 7 of the heat storage container, to form a heat medium flow channel 8 in the heat storage container. According to this constitution, the clearance can be secured even in changing phases, and the heat storage device of high heat transferring property can be provided.
