PROBLEM TO BE SOLVED: To obtain a three-dimensional netlike body bendable at arbitrary parts. SOLUTION: A great number of continuous filaments which are composed of a thermoplastic synthetic resin and have 0.1-1.5 mm thickness are piled in a netlike form, fused, bonded and integrated at their crossing points to form a netlike body having 0.1-4 mm substantial thickness. The netlike body is a three-dimensional netlike body of mat shape which is waved in an uneven state in a cross section in the thickness direction, has 4-50 mm apparent thickness and is provided with large voids by unevenness of the netlike body. The netlike body is provided with a belt-like readily bendable belt made flat by pressing in the length direction of the three-dimensional netlike body intermittently in an arbitrary width in the whole width.
