センサ装置
Document Type and Number:
Japanese Patent JP7026525
Kind Code:
B2
Abstract:
To provide a sensor device capable of preventing, without an increase in the number of components, erroneous detection due to electrostatic coupling occurring when an operation piece approaches.SOLUTION: A sensor device 1 comprises: an insulating substrate 11; a touch sensor TS having, on a first surface arranged on an operation surface side, a sensor electrode 12 formed on one principal surface 11a of the insulating substrate 11, and a first shield part 13 formed at least in a portion around the sensor electrode 12; and a detection electrode 14 which is arranged to face a shield electrode 131 included in the first shield part 13 and is provided on a second surface 15b that is different from the first surface 15a. The first surface 15a is located closer to the operation surface side than the second surface 15b. The shield electrode 131 and the detection electrode 14 constitute a pressure-sensitive sensor for detecting changes in a capacitance value caused when the shield electrode 131 and the detection electrode 14 approach each other.SELECTED DRAWING: Figure 1A
