PURPOSE:To prevent a substrate at the lower part of an electrode terminal from being cracked by a method wherein an extraction part of a wiring conductor connecting a bump as the electrode terminal to an internal device is formed so as not to contain a bent corner. CONSTITUTION:A wiring conductor 2 connecting an electrode terminal 1 to an internal device is extracted from the electrode terminal 1 so as not to contain a bent corner. That is to say, an extraction part 3 is straight and a bent part is not formed. Accordingly, when the electrode terminal 1 is connected to an external lead wire, a stress due to heat is not caused. Even when a bent part 4 is formed, this bent part 4 does not exist at the extraction part 3 but is installed in a region which is not affected by heat during connection of the wiring conductor 2; accordingly, the stress due to heat during connection to the external lead wire is not caused at the electrode terminal 1. By this setup, it is possible to prevent a substrate at the lower part of a bump from being cracked. |
