The present invention provides a method for producing a ciliary marginal zone stem cell induced to differentiate from a pluripotent stem cell, including either the following step (1) or step (2), or both of these steps: (1) a step of floating culturing cells obtained from a cell aggregate containing a ciliary marginal zone-like structure induced to differentiate from pluripotent stem cells, thereby obtaining a retinosphere and (2) a step of collecting stage specific embryonic antigen-1 positive cells from cells obtained from a cell aggregate containing a ciliary marginal zone-like structure induced to differentiate from pluripotent stem cells. According to the present invention, a ciliary marginal zone stem cell having differentiation potency into a retinal cell including a retinal layer-specific neuron and self-replication ability can be produced efficiently with a high purity.
