A heat-storing vessel filled with a heat-storing material of latent heat type is provided with a fluid flow passage in thermal contact with the heat-storing material for passing a fluid for storing and releasing heat. By passing a hot fluid through the fluid flow passage, the heat-storing material in the heat-storing vessel is melted to store heat. By passing a cold fluid through the fluid flow passage, the heat-storing material in the heat-storing vessel is solidified to release heat. The heat-storing material contains a gelling agent to suppress a phase separation phenomenon. A low temperature part is provided at a part of the heat-storing vessel and the heat-storing material containing the gelling agent is retained in a solid state at the low temperature part to prevent supercooling of the heat-storing material.
