Abstract
The present invention provides an elastic network structure that has excellent cushioning properties and makes less sound when it is compressed and recovers its shape. A network structure including a three-dimensional random loop bonded structure obtained by forming random loops by curling treatment of a continuous linear structure comprising a thermoplastic resin, and by making each loop mutually contact in a molten state to weld the majority of contacted parts, wherein (a) the continuous linear structure is a hollow cross section, (b) the degree of hollowness of the hollow cross section is not less than 10% and not more than 50%, (c) the fiber diameter of the continuous linear structure is not less than 0.10 mm and not more than 0.65 mm, and (d) the number of bonded points per unit weight of the random loop bonded structure is not less than 200/g and less than 500/g.
