Title:
TOUCH SENSOR DEVICE
Document Type and Number:
Japanese Patent JP2019046405
Kind Code:
A
Abstract:
To provide a high-quality touch sensor device capable of improving visibility of a display unit by resolving such a phenomenon that irregular reflection due to irregularity on a surface of printedly-formed wiring patterns, caused by an external shape of conductor particles is generated to cause appearance of the wiring pattern.SOLUTION: The touch sensor device includes at least: a printed-wiring board 40 on which wiring patterns (wiring layers 41 and 43) are formed on a substrate 31, the wiring patterns formed of a cured material of a conductive ink including conductor particles; and a front cover 50 that has a plate surface in parallel with the printed-wiring board 40, that is comprised of a transparent dielectric body, and, one surface of which is defined as a contact input surface 50a. The wiring patterns are formed on one surface side of the substrate 31, in the opposite side of a side where the front cover 50 is located.SELECTED DRAWING: Figure 2
