PROBLEM TO BE SOLVED: To provide a lamination indicator which prevents the deterioration of a yield in the manufacture of a multilayer board with a plurality of disposed unit boards, and also to provide a multilayer-board manufacturing system, and a manufacturing method for the multilayer boards. SOLUTION: The presences of the defective pieces of a work board in an internal layer are inspected by a picture recognizer 60. When there are the defective pieces, an defective information 200 is formed containing the work ID of the work board and the information of the places of the defective pieces, and output to an exposure system 4. The exposure system 4 specifies the presences of the defective pieces of the board in the corresponding internal layer on the basis of the defective information 200 when the work board is exposed for an external layer. The exposure system 4 changes a drawing data for an exposure and conducts the exposure so that discriminating marks indicating the defective pieces are exposed at the places of the existences of the defective pieces when there are the defective pieces. The combination of the boards in which the places of the defective pieces matches is obtained on the basis of the defective information 200, and the work ID of the obtained combination is generated as a laminating indicating information 300, and output to an output section 10.
