To provide a denture base manufacturing method for manufacturing a denture base while mitigating a workload on a technician.SOLUTION: A denture base manufacturing method includes: preparing a workpiece mold including a molding space； attaching a first bar member and a second bar member to the workpiece mold； injecting a denture base material into the molding space； disposing a plate-like member on the workpiece mold so that the plate-like member covers the first bar member and the second bar member from above and part of an aperture of the workpiece mold； polymerizing the denture base material to mold a workpiece including the polymerized denture base material and the first bar member and the second bar member； cutting part of the polymerized denture base material using a cutting device to manufacture a denture base with bar members； and removing the first bar member and the second bar member from the denture base with bar members denture base to manufacture a denture base.SELECTED DRAWING: Figure 3【課題】技工士の作業負担を軽減しつつ作製する義歯床製造方法を提供する。【解決手段】義歯床の製造方法は、造形空間を有する被加工物成形用型を準備すること、第１棒部材および第２棒部材を被加工物成形用型に取り付けること、造形空間に義歯床用材料を注入すること、第１棒部材および第２棒部材の上方かつ被加工物成形用型の開口の一部を塞ぐように被加工物成形用型に板状部材を配置すること、義歯床用材料を重合し、重合された義歯床用材料と第１棒部材と第２棒部材とを有する被加工物を成形すること、被加工物の重合された義歯床用材料の一部を切削装置によって切削し、棒部材付き義歯床を作製すること、棒部材付き義歯床から第１棒部材および第２棒部材を取り除いて義歯床を作製すること、を包含する。【選択図】図３
