The invention belongs to the technical field of tobaccos, and particularly relates to a tobacco material for smoking and a preparation method thereof. The tobacco material is in a sheet or film shape and is 0.1-2 mm thick. The tobacco material is prepared from, by mass, 10-50 parts of tobacco powder, 20-50 parts of a tobacco extract, 10-30 parts of an aerosol generating agent, 0.1-5 parts of heat conductive materials, 1-5 parts of polyethylene glycol and 1-5 parts of an adhesive. The tobacco material has the advantages that the heated condition of the tobacco material is improved by adding the heat conductive materials into the tobacco material, and the smoke density is well improved; by evenly scattering the heat conductive materials in the polyethylene glycol solution, the tobacco material heated uniformity is improved, and the smoke release uniformity is obviously improved; the tobacco material application range is wide.
