- stress is applied to the portion of the conductive wire 22 where the sag occurs, which may result in disconnection.
- the folding position of the conducting wire 22 varies depending on the apparatus and equipment.
- the conducting wire 22 is routed a long distance and fixed directly to the electrode 25b. Therefore, the drawn lead wire 22 is easy to unwind in the direction of the folding position, and the lead wire 22 to be thermocompression-bonded does not sufficiently ride on the electrode 25b.
