Abstract: A heat storage reactor, comprising: a plurality of heat storage layers including first flow paths through which a first fluid can flow, each of the first flow paths being filled with heat storage materials; and a plurality of heat exchange layers including second flow paths through which a second fluid can flow. In the heat storage reactor, the plurality of heat storage layers and the plurality of heat exchange layers are alternately stacked. Further, open ends for the second flow paths are formed on a surface different from a surface on which open ends of the first flow paths are formed. Furthermore, at least a part of the second flow paths is formed in parallel to the first flow paths.
