PURPOSE:To prevent lead wire terminals from being brought into imperfect contact and from falling out and to form a large number of lead wire terminals efficiently by a method wherein lead wires inserted into the inner bottom of a bottomed open container are attracted and held by using an electrode jig arranged at the outer bottom of the container and, in this state, aluminum flat parts are immersed and formed in a formation liquid. CONSTITUTION:One or more pieces of steam vents 2 are made in the trunk part of a bottomed open container 1; lead wire terminals composed of lead wires 4 welded to aluminum wires having flat parts 3 are inserted into this bottomed open container 1 in such a way that the lead wires 4 come into contact with the inner bottom of said container 1. An electrode jig 5 having magnetism is installed at the outer bottom of the container 1 where the lead wire terminals have been housed in this manner; the electrode jig 5 is connected to an anode of a power supply 6. In this state, the lead wires 4 are attracted and held due to magnetism of the electrode jig 5; even when they are turned upside down, they do not fall out. The lead wire terminals which have been housed into the container 1 in this manner are immersed into a formation liquid 8 in a formation tank 7; because the height of the flat parts 3 is even, it is possible to immerse them into the formation liquid down to the same position. |
