PROBLEM TO BE SOLVED: To suppress the entry of a heat storage material into a flow path for water vapor.SOLUTION: A reactor 20 includes a reaction vessel 22, a heat storage material 30 including an aggregation of heat storage particles P, for producing heat with hydration reaction caused by water vapor W and storing heat with dehydration reaction caused by heating, and a filter 40 having through-holes 42 a pore size d of each of which is five times or smaller an average particle size Da of the heat storage material 30. Here, the pore size d of each of the through-holes 42 is set to be five times or smaller the average particle size Da of the heat storage particles even when the heat storage material 30 is expanded by the hydration reaction and part of the heat storage material 30 is collapsed into a heat storage particle form. This suppresses the entry of the heat storage material 30 into a flow path 23 because the number of the heat storage particles P passing through the through-holes is reduced. |
