Invention-wise three-dimensional net made by warp knitting has high shape retainability in three-dimensional cords defining three-dimensional mesh spaces, capability of suppressing direction dependency, superiority in structural stability and pressure resistance, capability of retaining a suitable degree of elasticity and formation of three-dimensional cords simply by imparting tension, high void content, and lightweight, which are suitable for various applications. Invention-wise three-dimensional net formed by warp knitting comprises a first mesh web, a second mesh web and connecting yarns 3 connecting the first and second mesh webs 1 and 2, on front and back sides of the net, with a required spacing therebetween; further comprises three-dimensional cords each formed by braids on the first mesh web and the second mesh web 1 and 2 and by the connecting yarns 3 front-to-back-wise passed between the braids 11 and 12 of the first and second mesh webs 1 and 2, said first mesh web 1 having larger mesh openings than those of the second mesh web 2. At least partly in each of said three-dimensional cords 4, said connecting yarns 3 are passed from a single braid 11 on the first mesh web 1 to a plurality of braids 21 on the second mesh web 2 so that said three-dimensional cord 4 has a width of at least one mesh openings 12 on the first mesh web 1.
