An injector with a coating head, for uniformly coating a heat sink paste onto a surface to be coated is provided, which includes a body, a piston, and a coating head, wherein the piston is pressed to force the heat sink paste out of the body through the coating head, and the heat sink paste is molded by the coating head into a shape suitable for uniformly coating the surface to be coated, and is also quantified. Moreover, a scraping surface is provided at the opening of the coating head, for scraping off the redundant heat sink paste from the steel plate and for smoothing the surface of the heat sink paste, in the case that a steel plate is used to assist the quantifying operation of the heat sink paste.
