To provide a method for preventing a green sheet arrangement error in a printing and laminating process of the green sheet and improving laminating accuracy simultaneously.

Prior to printing, first and second reference holes H1 and H2, and a third reference hole H3 are arranged outside a print range of the green sheet as arrangement indexes for printing and laminating of the green sheet. Then, a suction hole for detection, which communicates with the third reference hole in a state where the green sheet is correctly fixed, is arranged on the stage of a printer. The printer is provided with a suction means to absorb air in the suction hole and a sensor to detect a pressure condition in the suction hole so as to judge that a print is not accurately arranged on the stage when the sensor detects a negative pressure.
