| 发明名称 | Capacitance type sensor | ||
| 摘要 | A capacitance type sensor includes: a dielectric layer made of a polymer; an elongated front-side electrode placed on a front side of the dielectric layer; an elongated back-side electrode placed on a back side of the dielectric layer; a front-side wiring connected to the front-side electrode; a back-side wiring connected to the back-side electrode; and a plurality of detection portions formed between the front-side electrode and the back-side electrode. Each of the front-side electrode and the back-side electrode has an elongated electrode body containing a binder and a conductive material, and an extended wiring portion extending in a longitudinal direction of the electrode body and having lower volume resistivity than the electrode body, and the front-side wiring and the back-side wiring have lower volume resistivity than the electrode body. | ||
