Zusammenfassung:	Provided is a method for manufacturing a flexible laminated board, comprising: a step for continuously feeding an insulating film comprising a liquid crystal polymer, and a metal foil, between endless belts; and a step for thermocompression bonding of the insulating film and the metal foil between the endless belts. The thermocompression step involves heating a flexible laminated board so that the maximum temperature of the flexible laminated board is within a range from 45 DEG C lower than the melting point of the liquid crystal polymer to 5 DEG C lower than the melting point, inclusive; and slow-cooling the flexible laminated board such that the exit temperature of the flexible laminated board, which is the temperature when conveyed out from between the endless belts, is within a range from 235 DEG C lower than the melting point of the liquid crystal polymer to 100 DEG C lower than the melting point, inclusive.
