Abstract (en)
Provided are a fiber structure which has moldability while having heat resistance, a molded body thereof, and a sound-absorbing material which uses the molded body. The fiber structure 12 comprises thermoplastic resin fibers formed from a thermoplastic resin having a glass transition temperature higher than or equal to 80°C, wherein the thermoplastic resin fibers have an average fiber diameter of smaller than or equal to 10 µm, and an elongation at break in at least one of a machine direction and a cross direction of the fiber structure is greater than or equal to 10%. The molded body 10 comprises at least the fiber structure 12 and a support 11. The molded body can cover an object 13 to be covered.
