PROBLEM TO BE SOLVED: To provide a new manufacturing method of a nonskid net for a tire capable of vulcanizing and molding the nonskid net in which spike pins are certainly buried without causing positional dislocation on each of mesh crossing parts of a mesh type net body. SOLUTION: An unvulcanized net body is fitted in a mesh type molding groove 21 after arranging the spike pins 2 buried in each of the mesh crossing parts of a nonskid net body 1 in the mesh type molding groove 21 formed on a female mold 20 for vulcanization, thereafter, the floating of the unvulcanized net body fitted in the mesh type molding groove 21 is prevented by placing a cover mold 40 on the female mold 20, and thereafter, the nonskid net body 1 on which the spike pins 2 are buried in each of the mesh crossing parts is vulcanized and molded by heating and pressing the unvulcanized net body by the female mold 20 and a male mold 30.
