TOUCH PANEL SENSOR AND TOUCH PANEL SENSOR WITH FLEXIBLE PRINTED WIRING BOARD

摘要

PROBLEM TO BE SOLVED: To provide a touch panel sensor capable of preventing peeling of an FPC and suppressing breakage in a connection wiring line of the FPC when used together with the FPC in a module.SOLUTION: The touch panel sensor includes: a transparent film substrate 1; a top electrode 2a formed on one surface of the transparent film substrate and a top wiring line 3a connected to the top electrode; a top external connection terminal 4a formed on a surface on the top electrode side of the transparent film substrate and connected to the top wiring line; a back electrode 2b formed on the other surface of the transparent film substrate and a back wiring line 3b connected to the back electrode; and a back connector connection part 15b formed on a surface on the back electrode side of the transparent substrate and connected to the back wiring line, for connecting a drive circuit board of a module. The transparent film substrate has a protruding part 11 protruding outward from an outer edge of the top external connection terminal. The back wiring line is formed on a surface on the back electrode side of the protruding part; and the back connector connection part is formed on an end of the protruding part.SELECTED DRAWING: Figure 1
