A network structure having excellent cushioning properties and reduced sound during compression and recovery from a compressed state is provided. A three-dimensional random loop formed by twisting a continuous linear body of 100 to 100,000 decitex to form a random loop, bringing the respective loops into contact with each other in a molten state, and fusing most of the contact portions. A network structure having a joint structure, wherein the continuous linear body is made of a polyester-based thermoplastic elastomer and R 1 —CONH—R 2 or R 1 —CONH— (CH 2 ) n —NHCO—R 1. A network structure comprising a composition containing a substituted amide having a structure, wherein the weight ratio of the polyester-based thermoplastic elastomer and the substituted amide is 100: 0.01-20. .
