There is provided a culture method and a culture device for efficiently producing cells and/or cell tissue suitable for medication applications. The culture method may include a first step of adhering the cells onto the electrode layer and culturing the cells thereon. The electrode layer may be coated with an oligopeptide including a terminal amino acid, a cell adhesive sequence, and an alternating sequence to be bound to the one end side of the cell-adhesive sequence. The alternating sequence may include a plurality of acidic amino acids and a plurality of basic amino acids that are alternately bound to each other one by one. The culture method may include a second step of applying, to the electrode layer having the cells adhered thereonto, an electrical potential inducing reductive desorption of the oligopeptide, to thereby detach the cells from the electrode layer.
