As shown in fig. 4 to 5, the substrate 1 includes a substrate body 101 and a first insulating layer 102, the substrate body 101 may be made of aluminum or an aluminum alloy, or may be made of other metal aluminum plating, and the first insulating layer 102 is an aluminum oxide film obtained by anodizing the substrate body 101.

The anti-sticking insulating layer 4 is made of microcrystalline glass or black microcrystalline glass. The microcrystalline glass can be insulated, residues of the baked tobacco products are not easy to adhere to the microcrystalline glass, the residues of the tobacco products adhered to the microcrystalline glass can be cleaned only by lightly wiping, and the baked tobacco products are convenient to clean. The black microcrystalline glass can enhance the heat radiation and increase the heat utilization rate.
The form of the substrate 1 includes at least two kinds, which are merely exemplified herein and not limited to only two kinds.
First (as in fig. 3): the matrix 1 is inserted into the smoking article and heated, and the matrix 1 is in a solid needle shape, a hollow needle shape or a sheet shape; and/or the diameter or width d of the substrate 1 is 1.5-2.5mm, preferably, the diameter or width d of the substrate 1 is 2 mm.

When the base 1 is provided with the accommodation cavity 108, the first heat generating unit 201 and the second heat generating unit 202 may also be provided in such a manner: a first insulating layer 102 is provided on the base body 101, and then a first heat generating unit 201, a first conductive unit 301, a second heat generating unit 202, and a second conductive unit 302 are provided on the first insulating layer 102. The base body 101 is simultaneously connected to the first and second heat generating units 201 and 202 through the common connection portion 109, and the first and second conductive units 301 and 302 are disposed at both ends of the base body 101.
