An object of the present invention is to produce a double-sided metal-clad laminate with excellent industrial productivity while having excellent interlayer adhesion between an insulating film and a metal foil, having no variation in adhesive strength, and suppressing appearance defects such as wrinkles. Provide a way that can be. A method of manufacturing a double-sided metal-clad laminate in which metal foils (B, B ′) are bonded to both sides of an insulating film (A) having an adhesive surface made of a thermoplastic resin, and having a heat capacity. (R 1 ) / (B) / (A) / (B ′) between the pair of pressure rolls (r 1 , r 2 ) using the separation film (C) in the range of 50 to 150 J / m 2 / (C) / (B ′) / (A) / (B) / (r 2 ) in order, insulating film (A), metal foil (B, B ′), and separation film (C ) Are stacked and thermocompression bonded, and then separated from the separating film (C) to obtain two double-sided metal-clad laminates.
