PROBLEM TO BE SOLVED: To provide a resin net which is embedded in embankment and under a slope for reinforcement. SOLUTION: A method for producing the resin net comprises the first process in which borehole parts arranged in parallel in the longitudinal direction and the cross direction are formed in a resin plate, the second process in which expanded parts are formed in the middle areas of the sides in the cross direction of the approximately rectangular borehole parts, and the plate is heated at a temperature allowing the plate to be stretched, the third process in which the plate is passed between rolls so that its longitudinal sides are stretched, the fourth process in which tension is applied in the orientation direction so that cross-directional sides and the expanded parts, which are non-orientation parts, are stretched to improve molecular orientation properties, and the fifth process in which left remaining heat is cooled to room temperature for winding. In Fig. 1 is the resin plate; 11 is a press (first process); 2 is hot water (second process); 13 is a rear roll (third process); 14 is a front roll (third process); 15 and 16 are re-orientation processes (fourth process); 30 is the final product (resin net).
