"Capacitive Touch Member, Manufacturing Method Therefor, And Capacitive Touch Detection Apparatus"

Abstract: [Object] To provide a capacitive touch member having a flexible shape or a stereoscopic shape and includes a light transmissive detection electrode, a manufacturing method therefor, and a capacitive touch detection apparatus including the capacitive touch member. [Solving Means] Produced is a capacitive touch member (10) including a film-like or plate-like support (1) that is formed of an insulating material and has a flexible shape or a stereoscopic shape, a detection electrode (2) that is arranged on at least a part of one surface of the support (1) and formed of a light transmissive conductive layer containing a carbon nano linear structure such as a carbon nanotube, and a lead-out wire (3) that is led out from the detection electrode (2). A capacitive touch detection apparatus is constituted of the touch member (10) and a capacitance detection circuit (60) that is electrically connected to the detection electrode (2) via the lead-out wire (3) and detects a change in capacitance due to approach or contact of a human body with respect to a touch surface (4). The detection electrode (2) may be coated with a protective film, and a surface of the protective film may be used as a touch surface. [Selected Drawing] Figs. 1
