PROBLEM TO BE SOLVED : To provide a cultivation device constructed by closely arranging a plurality of hollow three-dimensional members set with an opening part (2) on the side face so as to supply a further large amount of air directly to the surroundings of roots, and let air freely flow in a culture medium, in view of the fact that conventionally, it is not easy for a cultivation container and a cultivation device using soil to take air into a culture medium because of the structure, and to increase air permeability requires air permeable materials or equipment and materials to take much labor and cost. SOLUTION : A cultivation device is constructed by bringing a plurality of hollow three-dimensional members (1), (1)... which have a square column form and whose at least upper end is opened, to an aggregate by mutually closely arranging side faces of at least one of each member (1), setting opening parts (2) connected to each other on at least each of the side faces adjacent to each other in a row, among each of the side faces of each of the members (1) forming the aggregate, and fastening the aggregate by fixtures.
