PROBLEM TO BE SOLVED: To improve heat exchanging performance by increasing the contact area of a heat storage means and a heat transferring wall while improving pressure resisting performance of the heat transferring wall. SOLUTION: This heat storage device comprises:the heat storage means 4 constituted by shaping a latent-heat heat storage agent which is solid in non-heat storage and a liquid in heat storage, into the flat plate shape and packing it in vacuum; and the heat transferring wall 5 retaining the heat storage means 4 in a state of holding it therebetween and having a concave and convex surface to transfer and receive heat to the latent heat-heat storage agent, and the heat storage means 4 also has a concave and convex surface oppositely to the concavity and convexity of the heat transferring wall 5. Thus the contact area of the latent heat-heat storage agent and the heat transferring wall 5 is increased, and the pressure-resisting performance of a path of the fluid exchanging heat with the heat storage means 4 through the heat transferring wall 5 is improved.
