The invention relates to the technical field of spine sticker and preparation thereof, in particular to a spine sticker with a far infrared heating layer and a preparation method thereof. The spine sticker comprises a plaster area and a sticking part, wherein the plaster area is adhered to the spine column of a human body, and the sticking part is arranged at two sides of the plaster area. The preparation method comprises the following steps of: uniformly spreading the plaster on an area with air-permeable through holes on first lining cloth, and immediately covering the second lining cloth onanother surface; combining a far infrared heating sheet with the surface of the second lining cloth which is not contacted with the plaster layer in step 1 and third lining cloth into a whole througha conductive line, and adhering the other surface of the first lining cloth with a transparent substrate to obtain the spine sticker. The spine sticker solves the problems of single function and complex preparation process of a prior spine sticker, and the prepared spine sticker has the effects of promoting blood circulation to removing blood stasis, high human body adhesion degree, temperature-rising and heating, and strengthening bones and muscles.
