PROBLEM TO BE SOLVED: To provide a heat accumulating unit enabling to reduce the number of part items, to reduce manufacturing costs with simplified manufacturing, and to secure a large heat accumulating capacity, resulting in high performance, and also to provide a manufacturing method thereof. SOLUTION: Cylindrical bottomed outer walls 16 having openings 15 on one end; fluid passage forming parts 20 formed with fluid passages 19 fluidizing the fluid with among of heat on an inner side than the outer wall 16; and accumulating material filling space forming parts 23 formed with accumulating material filling spaces 22 filled with the accumulating material on the inner side than the outer wall 16 and adjacent to the fluid passage 19 are integrated. This unit comprises: at least two main members 12 installed at front and rear portions so that the openings 15 are opposed to each other; separators 39, 43 separating adjacent main members 12; and cover members 46 arranged on the front side of the main member 12 at the front end, and on the rear side of the main member 12 at the rear end, respectively.
