Title:
TOUCH PANEL AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2016/002279
Kind Code:
A1
Abstract:
Provided are: a touch panel wherein a terminal part of a sensor main body and a terminal part of a circuit board are reliably connected electrically in cases where the terminal part of the sensor main body that constitutes the touch panel is formed by filling a groove with a conductive material; and a method for manufacturing this touch panel. A touch panel (10) is provided with a first electrode-side terminal part (42A) that is electrically connected to an upper detection electrode (36A). The first electrode-side terminal part (42A) is configured of a first resin layer (44a), which is arranged on a first substrate (34A) and is provided with a first terminal groove (54a), and a first conductive material (48a) that is filled into the first terminal groove (54a). A flexible printed board (28), which is a circuit board, is laminated on the first electrode-side terminal part (42A) with an anisotropic conductive film (60), which contains conductive balls (61), being interposed therebetween. An anisotropic conductive film which contains conductive balls (61) that have an average particle diameter (x) satisfying specific relations with the size (a) of the first terminal groove (54a) in the width direction and the depth (c) of a gap (64) that is formed in the first terminal groove (54a) is selected as the anisotropic conductive film (60).
