Abstract

A network structure is disclosed including a three-dimensional random loop bonded structure obtained by forming random loops with curling treatment of a continuous linear structure including at least one thermoplastic elastomer selected from a polyester-based thermoplastic elastomer, a polyolefin-based thermoplastic elastomer, and an ethylene-vinyl acetate copolymer, and by making each loop mutually contact in a molten state, wherein a fiber diameter of the continuous linear structure is not less than 0.1 mm and not more than 3.0 mm, a fiber diameter of a surface layer portion of the network structure is not less than 1.05 times of a fiber diameter of an inner layer portion thereof, an apparent density is not less than 0.01 g/cmand not more than 0.20 g/cm, 750 N-constant load repeated compression residual strain is not more than 15%, and 40%-compression hardness retention after 750 N-constant load repeated compression is not less than 55%.
