PROBLEM TO BE SOLVED: To provide a fibrous structure having a good feeling and excellent in elasticity and durability. SOLUTION: This fibrous structure is composed of a polyester-based heat- bonding conjugate staple fiber and a polyester-based staple fiber so as to have a weight ratio of the heat-bonding conjugate staple fiber to the staple fiber of 5:95 to 70:30, and further constituted so that at least a part of intersections of the heat-bonding conjugate staple fiber with the staple fibers and/or with other heat-bonding conjugated staple fibers are thermally bonded to form fusion points. The polyester-based heat-bonding conjugate staple fiber is composed of a thermoplastic polyester-based elastomer (E) and a polyester (P) having a melting point which is 10 deg.C or more higher than that of the elastomer (E) so as to have a ratio of E:P in the fiber cross-section areas of 20:80 to 80:20, and further arranged so that at least a part of the elastomer (E) is exposed onto the surface of the staple fiber. A polytrimethylene terephthalate-based polyester staple fiber or a conjugate staple fiber containing at least the polytrimethylene terephthalate-based polyester as a component is used as the polyester-based staple fiber.
