description PROBLEM TO BE SOLVED: To improve quality of a printed wiring board by eliminating lamination displacement between core materials superposed on each other when executing lamination press of a core laminate substrate of the printed wiring board. SOLUTION: In a process of lamination press of a printed wiring board, a property of keeping a contact part to a lamination press device 9 flat and absorbing displacement and pressure in lamination press processing is provided to a structure of a core laminate substrate 11 comprising core materials 7 and a prepreg 8; lamination press is executed by a structure where shock-absorbing materials 13 easily separable from the structure of the core laminate substrate 11 are added on the upper and lower sides, whereby displacement in lamination between the core materials 7 superposed on each other and warpage of the core laminate substrate 11 are prevented.
