The invention relates to a production method of a prestressed wire with a small transmission length, which mainly aims to solve the problem of gradual cracking of both ends of a member in service because no prestress exists in the both ends of the member due to a certain transmission length of the both ends of the member when the prestress is established by virtue of the binding force of the prestressed wire and concrete after relaxation in the prior art. On an existing production line of a spiral rib steel wire, after the steel wire is drawn by a hard alloy smooth round mold, the strength of the steel wire is reduced after being heated at the moment, a plurality of heading-shaped bulges are processed on the surface of the steel wire by using a three-high mill at a certain distance, the distance between adjacent bulges is adjusted according to the length and stretching extension of the member, and the heading-shaped bulges can be tightly pressed against the ends of the member after relaxation. The production method has the advantages that the transmission length of the prestressed wire after relaxation for establishing the prestress can be eliminated or reduced, so that the whole member is protected by the prestress, and the ends of the member are prevented from cracking and damaging.
