活物質ペーストの充填時の妨げとなり、工程が複雑化さ
れ、連続生産ができない。■ To avoid filling the active material paste into the lead terminal welding area, press the board to make it denser, or cover it with masking tape, and after filling the active material paste, remove the high-density area or the masking tape. Method of welding a lead terminal to the y-de terminal ◇ In both of these methods, the exposed part of the electrode substrate and one pole surface of the y-de terminal are spot welded. Here ■ and ■
In this case, the pre-welded lead terminals and masking tape interfere with filling the active material paste, complicating the process and making continuous production impossible.

を有している。■In order to directly weld the electrode board and lead terminal,
An insulator such as an active material must not be present at the 1@contact portion of the positive electrode plate, and it is impossible to ensure that the metal surface of the electrode substrate is exposed. However, it is very difficult to completely remove the active material filled in the electrode plate. If active material particles are present, sparks may occur, resulting in poor welding.
