The invention provides a manufacturing method of a high-power vertically-wound air-cooled electric reactor and the electric reactor. The manufacturing method comprises the following steps that an iron core is installed on a lower yoke; flat wires are made into a plurality of wire turns, and the wire turns are sequentially arranged on the iron core in a sleeving mode; the inter-turn gap is filled with a positioning structure used for reducing relative movement between the adjacent wire turns, so that the multiple wire turns form an integrally fixed coil; the upper yoke covers the coil, and then a fastener penetrates through the mounting lugs of the upper yoke and the lower yoke to tension the plurality of wire turns and the positioning structure filled in the inter-turn gap part; and the terminals are respectively arranged on the upper yoke and the lower yoke and are connected with the coil to form the reactor. According to the invention, through the thermal shrinkage cloth with the wave-shaped positioning str
