PROBLEM TO BE SOLVED: To provide a flexible concrete structure and its molding method, capable of performing the sufficient effect, when requiring flexible performance such as causing deformation in the structure by external force such as an earthquake, for preventing the deterioration, without being always exposed to outside air and water, since a flexible expansion material is embedded in a concrete structure 2, by being covered with a covering material provided with a space part for securing a shape changing room on the periphery, while remarkably shortening work time by finishing embedding work of the flexible expansion material 3 only by placing concrete one time. SOLUTION: The flexible expansion member 3 is formed by covering an expandable material 31 causing a shape change with the covering material 33 for securing the space part 32 capable of the shape change on the outer periphery. The expansion member 3 is built in the concrete structure 2. COPYRIGHT: (C)2005,JPO&NCIPI
