PURPOSE:To restrain deviation of inner layer members or the like in a lamination bonding process by a maslamination method, and enable coping with the change of thickness of the whole laminate on account of the change of board thickness or lamination condition, by employing one kind of shift-preventing metal plate. CONSTITUTION:In a lamination bonding process by the maslamination method of a multilayered board, an expansion structure 13 is employed for the shift- preventing clamp of a shift-preventing metal plate 1 which prevents the shift of inner layer plates 6 or metal plates 5a, 5b, and a laminate is formed by heating and pressing. The expansion structure 13 expands when pressure is not applied from a lamination press heating platen 3 or the like, and contracts when the pressure is applied. |
