PROBLEM TO BE SOLVED: To provide a heat storage apparatus which can form a uniform temperature layer even when a water depth is shallow and which has a high heat storage tank efficiency. SOLUTION: The heat storage apparatus comprises header pipes 121 to 124 arranged on upper parts and lower parts of heat storage tanks 101 to 108. The apparatus further comprises a plurality of branch pipes 111 each having a diameter smaller than that of each of the pipes 121 to 124 and connected to the pipes 121 to 124. The apparatus also comprises a distributor 112 having a plurality of holes and connected to the pipes 111. In this case, the plurality of holes are provided in a row state at both ends of a line along an axial direction at a part except a cylindrical wall opposed to a connecting part of the pipe 111 at an opposite side of the connecting part to the pipes 111. The tanks 101 to 108 communicate with adjacent tanks through communication ports 151, 152. The ports 151 are provided at lower parts of the tanks 101 to 108, and the port 152 are provided at upper parts of the tanks 101 to 108.
