The invention discloses a heating non-combustible smoking set metal substrate rare earth thick film heating sheet making method. The method comprises the following steps of S1, substrate stamping, S2, surface treatment, S3, insulating layer making, S4, heating thick film slurry printing: screen printing rare earth thick film slurry is used outside the insulating layer, the printing thickness is controlled to be 0.05 to 0.1 mm, and then, heating and curing are carried out to form a rare earth thick film electrode, S5, connection circuit printing and S6, protection layer printing. The above making method has a simple processing step, the operation is easy, the above technical scheme overcomes the defects of high production cost, high risk coefficient and easy explosion of the conventional MCH ceramic heating body in the technical field of smoking sets, the rare earth thick film material is applied to the smoking set field to make a heating sheet, the production cost is greatly reduced, damage is not easy, the safety coefficient is high, wide promotion is easy, and the prepared product is high in conversion efficiency, good in insulation, quick in heating speed and good in use effects.
