PURPOSE:To safely and storage heat in a small scale by embedding a heat pipe equipped with heat transfer fins and an electric heater into a heat storage powder body whose heat capacity is specific per unit volume. CONSTITUTION:A heat storage device T is designed to fill up heat storage fine particles 1 in a cylindrically shaped vessel 5. A heat pipe 2 equipped with a number of heat transfer fins 4 and an electric heater are embedded in the fine particles 1. The heat storage fine particles comprise ceramics having a thermal capacity of 0.5cal/cm .k and over, and a heat conductivity of 0.5kcal/ m.h.k and over and a heat resistant temperature of 500 deg.C and over. The heat pipe 2 is equipped with a plurality of heat transfer fins 4. The heat storage device T is designed to maintain the fin particles 1 at a temperature of 500 deg.C and over by supplying power to the electric heater 3 and take out his heat by way of the heat pipe 2, if necessary. Since this device uses the fine particles 1 whose thermal capacity is large, it is possible to carry out small scale, efficient and safety heat storage.
