The invention discloses a heat insulation aluminum plate for an automobile exhaust pipe. The heat insulation aluminum plate comprises a plurality of convex parts and concave parts, wherein the convex parts and the concave parts are sequentially and alternately distributed, at least one micro passing hole is formed in each convex part and/or each concave part, and the hole diameter of each micro passing hole is 0.2mm to 1mm. In addition, a plurality of convex-concave embossing patterns are formed on the heat insulation aluminum plate, so the effect of improving the rigidity of the heat insulation aluminum plate is achieved; in addition, a plurality of micro passing holes are formed in the heat insulation aluminum plate, so the effect of sound absorption is achieved. The rigidity of the heat insulation aluminum plate is higher, and the thickness of the heat insulation aluminum plate is reduced on the premise that the new structure reaches the same performance, so the cost is reduced, meanwhile, under the condition that the hole diameter is unchanged, the heat insulation aluminum plate with the thinner thickness is more favorable for absorbing the high-frequency noise of an automobile.
