The invention discloses an automotive power-assisted steering electric controller good in heat conductivity. The automotive power-assisted steering electric controller comprises a printed circuit board (PCB), a base and a cover plate. Tapered support columns and a heat-conducting seat are integrally formed on the base. The PCB is disposed on the tapered support columns and located through two locating columns penetrating through the PCB, and the PCB is fixed to the heat-conducting seat by the combination with screws. Mounting notches are formed in each of the left side and the right side of the base, and mounting protrusions which are identical to the mounting notches in number, correspond to the mounting notches in position and are matched with the mounting notches in size are arranged on each of the left side wall and the right side wall of the cover plate. The base and the cover plate are arranged together in a press fit mode. The mounting protrusions are inserted into the corresponding mounting notches, the tapered support columns are disposed in the cover plate, the cover plate and the base are made to be fastened tighter and tighter, and a circular mistaken-mounting prevention mark is arranged at the position, close to the front left corner, of the top of the cover plate. By means of the structure of the automotive power-assisted steering electric controller, the problems of slight shaking between the base and the cover plate as well as between the PCB and the base after mounting and too high local temperature of the PCB are effectively solved, and the cover plate is prevented from being put reversely.
