FLEXIBLE WIRING MEMBER, ACTUATOR, LIQUID DISCHARGE HEAD, AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To solve a problem in which: a flexible wiring member obtained by connecting a FPC and a FFC may have disconnection or cracks at an end of the junction thereof.

SOLUTION: An electrode 302 of an FPC 15 and an electrode 312 of an FFC 16 are connected by soldering. A solder fillet 320 is formed in a substantially triangle shape with an acute top-most edge 312b on an apical surface 312a of the electrode 312 of the FFC 16 as an apex and a front-back direction of the electrode 302 of the FPC 15 as the base, and covers the apical surface 312a of the electrode 312 of the FFC 16.
