The invention relates to a manufacturing method for a high-conductivity composite pipe and belongs to the field of composite pipes. The manufacturing method comprises the following steps that a pipe columnar male die is prepared, and the surface of the male die is coated with a demolding material; the surface of the demolding material is coated with a laying layer in a laid mode, and the laying layer is fiber reinforced composite material prepreg cloth; a BOPP belt is wound tightly on the surface as a process skin; warming solidification is conducted, and heat preservation is conducted for at least 1.5 hours at the temperature being 125 DEG C+/-5 DEG C; the columnar male die is removed in a physical drawing mode, and a composite inner skin is obtained; the BOPP belt is ripped off, and surface polishing is conducted; an adhesive film, a metal net and an adhesive film are sequentially laid on the surface of the composite inner skin, a metal pipe connector is installed, the effect that the metal pipe connector makes contact with the metal net closely is ensured, good breakover is achieved, fiberglass prepreg cloth is laid overall finally, and an outer skin is formed; a BOPP belt is wound tightly on the surface as a process skin; warming secondary solidification is conducted, and heat preservation is conducted for at least 1.5 hours at the temperature being 125 DEG C+/-5 DEG C; and the surface is finished, machining is conducted, the metal pipe connector is fixed through a screw, and the needed high-conductivity composite pipe is obtained.
