A topping extruding die is provided to allow a single cord connection portion to continuously pass a hole of the extruding die while constantly maintaining the gap between cords. A topping extruding die includes an upper die(2) having hemispherical cord guide holes and a lower die(3) having hemispherical cord guide holes. A leaf spring(4) made of a metal material is built in the upper die in such a manner that the leaf spring contacts the cord guide holes of the upper die. The leaf spring is protruded further than the upper die by 0.5 to 2mm.
