To provide a method for manufacturing a panel member which prevents light leakage and can obtain clear characters and figures.SOLUTION: A method for manufacturing a panel member 1 includes: a step of printing a print layer 4a formed of ink not transmitting light on a surface side of a resin sheet 3; a step of overlapping the print layer 4b on the upper surface of the print layer 4a and printing the print layer to form a laminated print layer 4; and a step of irradiating the surface side of the laminated print layer 4 with a laser beam to remove a part of the laminated print layer 4, and forming a hole part of which an end face is vertical on the laminated print layer 4.SELECTED DRAWING: Figure 3
【課題】光漏れを防止して、鮮明な文字や図形を得ることができるパネル部材の製造方法を提供する。【解決手段】本発明のパネル部材1の製造方法は、樹脂シート3の表面側に、光を透過しないインクからなる印刷層4aを印刷する工程と、印刷層4aの上面に印刷層4bを重ねて印刷して、積層印刷層4を形成する工程と、積層印刷層4の表面側からレーザ光を照射し、積層印刷層4の一部を除去して、端面が垂直である孔部を積層印刷層4に形成する工程とを備えている。【選択図】図3
