  "textContent": "The present invention provides a network structure having excellent repeated compression durability, a low repeated compression residual strain and a high hardness retention after repeated compression. A network structure made of 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 elastic resin selected from the group consisting of a polyolefin-based thermoplastic elastomer, an ethylene-vinyl acetate copolymer, a polyurethane-based thermoplastic elastomer and a polyamide-based thermoplastic elastomer, the continuous linear structure having a fineness of not less than 100 dtex and not more than 60000 dtex, and by making each loop mutually contact in a molten state, wherein The network structure has an apparent density of 0.005 g/cm 3 to 0.20 g/cm 3 , a 50%-constant displacement repeated compression residual strain of not more than 15%, and a 50%-compression hardness retention after 50%-constant displacement repeated compression of not less than 85%.",
