The production device 100 comprises a top plate 110, pins 120A to 120D, a first slide plate 130, a second slide plate 140, a stopper 150, a base plate 160, an outer peripheral needle-shaped member 170 and an inner peripheral needle-shaped member 180. Cell aggregates 400 are put into a three-dimensional tubular space S1 that is defined by the outer peripheral needle-shaped member 170 and the inner peripheral needle-shaped member 180. Then, the top plate 110 is pressed downward on the accumulated cell aggregates 400. Thus, the cell aggregates 400 are immersed in a culture solution 210 and stuck together so that a tubular cell structure 500 is produced using the three-dimensional space S1 as a mold.

A neutron ray irradiation target apparatus 100 of the present invention is used to irradiate irradiation targets (seeds, etc.) with a neutron ray generated by a neutron ray irradiation apparatus. The neutron ray irradiation target apparatus 100 has a holding means 70 for holding the irradiation targets. The holding means 70 holds at least one closed container 30 which can accommodate the irradiation targets 20 stacked randomly and three-dimensionally. In the case where the irradiation targets are stacked three-dimensionally and accommodated in the closed container, the irradiation targets overlapping each other are irradiated with the neutron ray in a chain reaction fashion. The neutron ray irradiation target apparatus 100 can be used in a method for irradiating a large amount of irradiation targets (seeds of crops, etc.) with a neutron ray, while reducing a required time, thereby efficiently inducing mutations in the irradiation targets.
