PROBLEM TO BE SOLVED: To manufacture a large-sized lithium target in which, for example, the diameter×thickness of a conjugate of an Li membrane/Cu cooling base is settled within the range of φ20 mm to 40 mm×100 to 200 μm±10 μm.;SOLUTION: A manufacturing method of a lithium target includes the steps of: placing, on a hot plate, a Cu cooling base constituting the lithium target; heating the Cu cooling base in a nitrogen containing atmosphere by means of the hot plate with the precision of 20 to 70°C±0.1°C; placing an Li membrane on the Cu cooling base while heating the Cu cooling base by means of the hot plate, and temporarily bonding both the Li membrane and the Cu cooling base by pressing them using a roller; and then detaching a conjugate of the Li membrane/Cu cooling base from the hot plate and joining both the Li membrane and the Cu cooling base within several seconds under the condition that the pressure is 15 to 25 MPa and the temperature is within the range of 20 to 70°C±0.1°C.;COPYRIGHT: (C)2014,JPO&INPIT
