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 × 10 4 and 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 ‰¤ X ‰¤ 17; 5 ‰¤ Y ‰¤ 25; if 5 ‰¤ X < 10, Y ‰¥ -2X + 25; and if 14 < X ‰¤ 17, Y ‰¤ -5X + 90.
