PROBLEM TO BE SOLVED: To provide a manufacturing method of an optical panel for aerial imaging, by which crack in a flat plate or damage in a light reflection layer does not easily occur when laminating and bonding the plural flat plates.SOLUTION: A manufacturing method of an optical panel for aerial imaging includes a laminate forming step of forming a laminate 3 by laminating and bonding plural flat plates 30. The laminate forming step includes: a flat plate arranging process of interposing strings of soft thin wire 6 between the flat plates 30 and arranging the plural flat plates 30 to form a flat plate aggregate 3'; a flat plate immersing process of making a fluid bonding agent 4a flow into a laminate forming container 5 to immerse the flat plate aggregate 3'; a thin wire withdrawing process of withdrawing the strings of thin wire 6 above the flat plate aggregate 3'; a pressing process of pressing one end surface or both end surfaces of the flat plate aggregate 3'; and a bonding agent curing process of curing the bonding agent 4a to allow the flat plate aggregate 3' to form into the laminate 3.SELECTED DRAWING: Figure 6 |
