PROBLEM TO BE SOLVED: To provide a heat accumulator capable of improving heat retaining property, while simplifying work for filling a heat accumulating material. SOLUTION: This heat accumulator 10 forms a heat accumulating module 11 from a plurality of plates 21. The plates 21 have a filling recess 71, a recess 72 for a passage, a recess 75 for a supply guide passage, a recess 73 for a discharge guide passage, a central heat accumulating material passing hole 74 and a corner heat accumulating material passing hole 76. A plurality of heat accumulating material filling spaces 36 are communicated by the central heat accumulating material passing hole 74 and the corner heat accumulating material passing hole 76 in a state of laminating the plurality of plates 21. The central heat accumulating material passing hole 74 and the corner heat accumulating material passing hole 76 are also arranged in the vicinity of the supply guide passage 34 and the discharge guide passage 35.
