PURPOSE: A thick plate mother-of-pearl sheet is provided which is economical by using fragments of a thin plate mother-of-pearl sheet, thereby obtaining sufficiently valuable patterns of mother-of-pearl, and has superior machinability of the cutting surface during laser cutting by using a laser-cutter. CONSTITUTION: The thick plate mother-of-pearl sheet (10) manufactured using thin plate mother-of-pearl sheet chips (10a) comprises a transparent plate (10b) material of synthetic resin having a thickness of 0.5 to 3 mm; a transparent adhesive (10c) coated on the plate; and thin plate mother-of-pearl sheet chips adhered on all over the surface of the plate by the adhesive, wherein the thick plate mother-of-pearl sheet further comprises a surface protective film of transparent synthetic resin material on the surface of the thin plate mother-of-pearl sheet chips (10a). The stringed musical instrument is inlaid with decorative patterns obtained by cutting the thick plate mother-of-pearl sheet using thin plate mother-of-pearl sheet chips into a certain shape as a position mark of a finger fingerboard, wherein the thin plate mother-of-pearl sheet chips comprise a transparent plate of synthetic resin material, a transparent adhesive material coated on the plate, and thin plate mother-of-pearl sheet chips adhered on all over the surface of the plate by the adhesive. The method for manufacturing the thick plate mother-of-pearl sheet using the thin plate mother-of-pearl sheet chips comprises a first process of coating transparent liquid phase epoxy, transparent liquid phase acrylic or transparent liquid phase formica as an adhesive on a transparent epoxy plate, transparent acrylic plate or transparent formica plate; and a second process of adhering thin plate mother-of-pearl sheet chips on the adhesive.
