<P>PROBLEM TO BE SOLVED: To provide a circuit board capable of obtaining high connection reliability. <P>SOLUTION: A flexible wiring board 123 as the circuit board includes wiring and an output terminal 2 constituting an end of the wiring. The output terminal 2 forms a protrusion stripe and a plurality of recesses 2a are provided in array on the surface opposite to a flexible base material 3 along the extension direction. Then, the maximum height roughness Rz of each recess 2a is smaller than that of each protrusion 2b between mutual respective recesses 2a. <P>COPYRIGHT: (C)2013,JPO&INPIT |
