The invention discloses a high-conductivity and high-strength metallized carbon nanotube film and a preparation method thereof. The preparation method comprises the following steps: providing an original carbon nanotube film, and sequentially carrying out oxidation treatment, sensitization treatment and activation treatment on the carbon nanotube film so as to form a palladium transition layer on the surface of the original carbon nanotube film; and forming a copper layer on the carbon nanotube film with the palladium transition layer to prepare the high-conductivity and high-strength metallized carbon nanotube film. The high-conductivity and high-strength metallized carbon nanotube film comprises a carbon nanotube film, a palladium transition layer and a copper layer which are arranged in sequence. According to the method provided by the invention, the palladium transition layer is introduced on the carbon nanotube film, so that the interface bonding of the carbon nanotube and copper is further improved, the
