However, in the above-mentioned conventional structure, as the pitch of the lead terminal portions 4 becomes finer due to high-density packaging, the outer lead portion 5 naturally also becomes finer, but this outer lead portion 5 is different from the adjacent outer lead portion 5. Since the direction g in between is not supported, it becomes difficult to maintain the strength. For this reason,
Cutting is likely to occur during forming of the outer lead portion 5. In addition, bridges are likely to occur when soldering with the wiring pattern, making the connection difficult. In addition, the outer lead portion 5 may float or deform, making it difficult to maintain dimensional accuracy, making it difficult to maintain fine pitch position. This has led to problems such as making it impossible to match and making handling during the manufacturing process difficult.

There are other fine-pitch connection methods, such as the flip-chip method in which the LSt chip is subjected to hump processing and bonded face-down directly to the wiring board, and the wire bonding method, but this method is particularly useful in the case of multi-chip connections. Since the LSI can only be tested in chip form, the yield of the LSI itself is poor. Furthermore, when mounting on a board, the defective rate increases due to stress such as temperature.
