<p><P>PROBLEM TO BE SOLVED: To prevent short circuit from occurring at soldering of the electrode land of a wiring member to the surface electrode of an actuator. <P>SOLUTION: The wiring member 11 include a substrate 55, a conductive wire material 64 provided on one surface of the substrate 55, and a covering member 59 covering the conductive wire material 64. The conductive wire material 64 has an electrode land 61 connected to a surface electrode 50, and a conductive wire 60 continuous with the electrode land 61. The covering member 59 has a first covering layer 56 which has a first opening 56a for exposing the electrode land 61, and a second covering layer 57 having a second opening 57a covering the first covering layer 56 and communicating with the first opening 56a. The second opening 57a is greater than the first opening 56a. The area of the surface electrode 50 is larger than an exposed area of the individual electrode land 61. The surface electrode 50 is projected partially toward an outside of the electrode land 61. The surface electrode 50 and the electrode land 61 are connected by solder 58 through the first and second openings 56a and 57a. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
