The invention discloses a leading-out terminal structure of a transformer coil. The leading-out terminal structure comprises a protective sleeve, wherein the sleeve body of the protective sleeve comprises a terminal protecting part and leading-wire protecting parts extending out from both sides of the terminal protecting part, a cutting joint is arranged on the sleeve body, and side wings with connecting holes respectively extend on the cut edges on both sides of the sleeve body. The protective sleeve is broken off at the cutting joint in the installing process to cover the leading-out terminal, a thread or rope is penetrated through the connecting holes, the side wings are tightly tied, and the exposed terminal is fully sleeved, therefore, the protective sleeve plays the roles of insulating, dust prevention and antifogging to the terminal. The invention also discloses a method for manufacturing the protective sleeve, a heat shrinkable tube is sleeved on a wooden pattern, and the parts where the side wings ar
