The invention discloses a preparation method of a vehicle-mounted iron-based amorphous powder core boost inductor, the inductor and an automobile, and relates to the technical field of new energy automobile power driving boost power. The method comprises the following steps: pressing iron-based amorphous powder; the pressed and formed iron-based amorphous powder core is engraved, and multiple sections of strip-shaped magnetic blocks are engraved on the iron-based amorphous powder core; the engraved iron-based amorphous powder core is annealed; the annealed iron-based amorphous powder core and accessories are assembled, and the size of an air gap after assembly is regulated and controlled by the thickness of a ceramic heat-conducting fin; carrying out integrated injection molding on the assembled inductor; and welding the inductor prototype with a copper bar terminal, and testing and packaging after ultrasonic cleaning to obtain the final inductor. The iron-based amorphous powder core small boost inductor with low loss is prepared, can achieve low working temperature and is suitable for a vehicle-mounted environment.
