A method for producing a thermoplastic liquid crystal polymer film excellent in thermal adhesion to an adherend made of a thermoplastic liquid crystal polymer film, a circuit board and a method for producing the same. The method for producing the film is characterized in that a thermoplastic liquid crystal polymer film is prepared as an adherend film and an adhesive film, respectively, and the adhered surface portion of the thermoplastic liquid crystal polymer film is subjected to X-ray photoelectron spectroscopy analysis at C (1s) (%) And Y (%) of the sum of the peak areas of [CO bond] and [COO bond] in the sum of the peak areas of the binding peaks caused by the X and Y X? Y? 65 (1) -8.0? Y-X? 8.0 (1) wherein, in the step of selecting or activating the thermoplastic liquid crystal polymer film as the adhesive film, (2). |
