PROBLEM TO BE SOLVED: To provide the equipment which is capable of surely supporting a material (superconducting material) so as to withstand vibration and acceleration (load) at the time of launching and also, capable of growing a large single crystal by heating and solidifying the material without bringing it into contact with any container or the like, in an agravity state. SOLUTION: In this equipment, a disk-shaped material 1 is inserted between two heater plates 2 and 3 and held with the heater plates 2 and 3 at the both surfaces of the material 1. In an agravity state, the single crystal growth using the equipment comprises: expanding the space between the two heater plates 2 and 3; then, positioning the disk-shaped material 1 between the two heater plates 2 and 3 by using a suspension rod 4 fixed in the central part of the disk-shaped material 1; thereafter, heating and melting the material 1 with the two heater plates 2 and 3 and also, dissipating heat from the material 1 through the suspension rod 4, to grow a single crystal from the central part of the material 1.
