A cultivation apparatus that cultivates a culture including a cell and/or tissue, the cultivation apparatus comprising: a culture bed on which the culture is disposed; an incubator unit that accommodates the culture with the culture bed; and a lever that penetrates from an inside of the incubator unit to an outside thereof, has an action unit at an edge thereof, and is movable in a circular arc around a fulcrum as a center, the fulcrum being set at a wall of the incubator unit or in the vicinity of the wall, characterized in that: the culture includes: a cell construct that includes a three dimensional scaffold where cells are disseminated, or a cell that is suspended in a culture fluid and enclosed in a bag or a tube of a semi-permeable membrane, or a cell and a gel scaffold enclosed in a bag or a tube of a semi-permeable membrane, in the culture bed, a disposing part and standing walls (138, 140) are included, the disposing part being formed by an elastic member having elasticity, the standing walls (138, 140) being opposite to each other, and the culture being disposed on the disposing part, each of the standing walls (138, 140) has a through hole, the through holes support both ends of the cell construct, or both ends of the bag or the tube, to hold the culture on the disposing part of the culture bed, and the action unit of the lever pushes a back side of the disposing part from the back side of the disposing part, to add a load to the disposing part, the disposing part is curved by the elasticity, and bending displacement is imparted to the culture. a culture bed on which the culture is disposed; an incubator unit that accommodates the culture with the culture bed; and a lever that penetrates from an inside of the incubator unit to an outside thereof, has an action unit at an edge thereof, and is movable in a circular arc around a fulcrum as a center, the fulcrum being set at a wall of the incubator unit or in the vicinity of the wall, characterized in that: the culture includes: a cell construct that includes a three dimensional scaffold where cells are disseminated, or a cell that is suspended in a culture fluid and enclosed in a bag or a tube of a semi-permeable membrane, or a cell and a gel scaffold enclosed in a bag or a tube of a semi-permeable membrane, in the culture bed, a disposing part and standing walls (138, 140) are included, the disposing part being formed by an elastic member having elasticity, the standing walls (138, 140) being opposite to each other, and the culture being disposed on the disposing part, each of the standing walls (138, 140) has a through hole, the through holes support both ends of the cell construct, or both ends of the bag or the tube, to hold the culture on the disposing part of the culture bed, and the action unit of the lever pushes a back side of the disposing part from the back side of the disposing part, to add a load to the disposing part, the disposing part is curved by the elasticity, and bending displacement is imparted to the culture. the culture includes: a cell construct that includes a three dimensional scaffold where cells are disseminated, or a cell that is suspended in a culture fluid and enclosed in a bag or a tube of a semi-permeable membrane, or a cell and a gel scaffold enclosed in a bag or a tube of a semi-permeable membrane, a cell construct that includes a three dimensional scaffold where cells are disseminated, or a cell that is suspended in a culture fluid and enclosed in a bag or a tube of a semi-permeable membrane, or a cell and a gel scaffold enclosed in a bag or a tube of a semi-permeable membrane, in the culture bed, a disposing part and standing walls (138, 140) are included, the disposing part being formed by an elastic member having elasticity, the standing walls (138, 140) being opposite to each other, and the culture being disposed on the disposing part, each of the standing walls (138, 140) has a through hole, the through holes support both ends of the cell construct, or both ends of the bag or the tube, to hold the culture on the disposing part of the culture bed, and the action unit of the lever pushes a back side of the disposing part from the back side of the disposing part, to add a load to the disposing part, the disposing part is curved by the elasticity, and bending displacement is imparted to the culture.
