INPUT DEVICE AND METHOD FOR MANUFACTURING SAME

摘要

Provided is an input device which has an improved wiring unit structure and can reduce changes in wiring resistance that occur over time. The input device is provided with a base plate comprising: a substrate; an electrode unit provided in an input region of a substrate surface; and a wiring unit electrically connected to the electrode unit in a non-input region of the substrate surface positioned outside of the input region. The wiring unit (16) is constructed from: a main wiring layer (29) that is formed from Cu; and a surface protective layer (30) that is formed on a surface (29a) of the main wiring layer (29) and comprises a Cu alloy having a film thickness that is thinner than that of the main wiring layer (29).
