A production method for a cerebral organoid having amyloid plaques is provided, the method including a step (a) of forming, in the presence of a SMAD inhibitor, an embryoid body from a pluripotent stem cell having a mutation in an Alzheimer's disease-related gene; a step (b) of embedding the embryoid body after the step (a) in an extracellular matrix and three-dimensionally culturing the embedded embryoid body in the presence of a SMAD inhibitor and a glycogen synthase kinase 3β (GSK3β) inhibitor to form an organoid; and a step (c) of removing the organoid after the step (b) from the extracellular matrix and subjecting the removed organoid to stirring culture in a medium, where at least a part of the step (c) is carried out in the presence of leukemia inhibitory factor (LIF).
