An object of the present invention is to prevent efflux of a heat storage material composition from a porous substrate in a heat reservoir. The heat reservoir of the present invention is characterized in that a porous substrate is impregnated with a latent heat storage material and a hydrogenated styrene-based thermoplastic elastomer. When the weight-average molecular weight of the elastomer is designated as X&#xd7;10and the amount of the elastomer is designated as Y parts by mass relative to 100 parts by mass of the latent heat storage material in the heat storage material composition, the following conditions are satisfied: 5&#x2264;X&#x2264;17; 5&#x2264;Y&#x2264;25; if 5&#x2264;X&#x3c;10, Y&#x2265;&#x2212;2X+25; and if 14&#x3c;X&#x2264;17, Y&#x2264;&#x2212;5X+90.

A method for dimensional stabilization treatment is disclosed which enables externally supplied high pressure steam to permeate well into interior of wood or wood composite, and which is thereby capable of constantly imparting high dimensional stability to the wood or wood composite. In the method, wood or wood composite W to be treated is held in a sealed space between two press platens 1a, 1b, and the sealed space is evacuated to establish reduced pressure therein, and thereupon, high pressure steam is supplied to the sealed space. The evacuation may be continued in parallel with the high pressure steam supply.
