In a culture method for adipocytes, seeded adipocytes are cultured while being allowed to adhere to a culture bottom surface (14) and walls (12) disposed perpendicularly to the culture bottom surface (14), without suspending the adipocytes in a culture solution, thereby obtaining mature adipocytes in which spherical lipid droplets having increased in size are generated within cells. This method uses a culture chamber (10) in which the walls (12) are formed perpendicular to the culture bottom surface (14). Spherical mature adipocytes containing spherical lipid droplets having increased in size within cells are cultured in a state where a cell or an aggregate of cells is allowed to adhere to two or more locations on the walls (12) and the culture bottom surface (14), thereby obtaining adipocytes having a shape similar to that of adipocytes in vivo.
