A high-temperature-resistant selective absorption functional membrane generated by thermal decomposition comprises a two-layer structure formed by compounding a metal base material (1) and a carbon material absorbing membrane layer (2); the structure of the high-temperature-resistant selective absorption functional membrane sequentially comprises a bottom layer of the metal base material (1) and a carbon membrane layer surface layer (2) that is formed after being treated by thermal decomposition and is provided with dense micropores; the bottom layer of the metal base material (1) is made from a board, or a pipe, or a pipe and a board, or pipes; the high-temperature-resistant selective absorption functional membrane (2) is formed by carrying out thermal decomposition treatment on an organic adhesive; the organic adhesive is made from a single material or more than one composite material; or a membrane layer is formed by mixing an adhesive and a light absorption material, and the carbon membrane layer surface
