The network structure is a network structure having a three-dimensional random loop bonding structure comprising a polyester thermoplastic elastomer continuous strand having a fiber diameter of not less than 0.1 mm and not more than 3.0 mm and a thermoplastic elastomer continuous strand of a polyolefin thermoplastic elastomer continuous strand, In the thickness direction of the network structure, a solid cross-sectional fiber main region mainly including solid cross-sectional fibers, a hollow cross-sectional fiber main region mainly including hollow cross-sectional fibers, and a solid cross-section fiber and a hollow cross- And the residual strain on the side of the main section of the meshed fiber and the residual strain on the side of the main section of the hollow section fiber are both 20% or less, and the residual deformation on the side of the main section side of the meshed fiber, And the difference from the residual strain is 10 points or less. |
