In this paper, we performed heat storage and heat collection throughout long term with a heat storage system of the solar heat use in the shallow-layer soil of depth around 2m and examined heat storage between seasons and possibility of the heat utilization. Heat storage layer in this paper is to construct in the shallow-layer soil, and it is a possible system that installation cost of the heat storage layer is held, because to shorten excavation quantity and piping length is possible, and because again, the insulation structure is unnecessary using the small of thermal conductivity of the soil. It can be said that the formation of heat storage layer which stabilized the shallow-layer soil is possible, because there is the annual change of the soil temperature of the heat storage layer outside about 4℃.
