<p><P>PROBLEM TO BE SOLVED: To provide a wiring board that improves long-term reliability to surely and strongly maintain electrical connection for a long time by preventing the interface of an electrode and a solder on the wiring board from being released by stress. <P>SOLUTION: A multi-layered wiring board having an electrode to be connected with a solder has an electrode structure wherein the outer periphery of the electrode rises along with a wall surface of a solder resist 5. A single-side wiring board that has an electrode to be connected with a solder and uses an insulating tape as a support, includes an electrode structure wherein the outer periphery of the electrode rises along a wall surface of the insulating tape. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
