Zusammenfassung:	PROBLEM TO BE SOLVED: To reduce construction period and cost. SOLUTION: The storage structure is provided with a lining layer 14 formed at the internal face of a cave 12, a pressure-resistant buffer layer 16, and an air-tight material 18, formed in bedrock 10. When constructing the storage structure, the bedrock is excavated to form the cave 12, and further, the lining layer 14 is formed to cover the excavated face of the cave 12. After the lining layer 14 has been formed, forms are installed in the inside of the lining layer 14a and reinforcements 24 and a joint material 26 dividing concrete to be placed thereafter into a plurality of sections along the peripheral and axial directions are arranged. Then, concrete is placed in the space 22. When the forms are removed, the storage structure in the bedrock is constructed as the outer peripheral edge of the air-tight material 18 is welded to the joint material 26.
