PROBLEM TO BE SOLVED: To provide a multilayer printed wiring board having high reliability, even when if using an anisotropic conductive film. SOLUTION: The multilayer printed wiring board is configured such that at least two printed wiring boards, each having an insulating substrate equipped with conductor circuits having different thicknesses on at least one surface of the front surface and the rear surface of the substrate are laminated, with the conductor circuits having different thicknesses made to face each other via the anisotropic conductive film.
