Abstract

Provided are a capacitance type touch member which has a flexible or stereoscopic shape and has a light transmissive detection electrode, and a method for producing the same; and a capacitance type touch detection device provided with the capacitance type touch member. A capacitance type touch member (10) comprised of a film-like or plate-like support element (1) composed of an insulating material, which has a flexible or stereoscopic shape; a detection electrode (2) which is disposed on at least a part of one surface of the support element (1), and is composed of a light transmissive conductive layer containing a carbon nano linear structure such as a carbon nanotube; and a lead wire (3) drawn from the detection electrode (2), is produced. A capacitance type touch detection device is comprised of the touch member (10) and a capacitance detection circuit (60) which is electrically connected to the detection electrode (2) via the lead wire (3), to detect the change of the capacitance due to the access or contact of a human body to a touch surface (4). The detection electrode (2) may be coated with a protection film, and the surface of the protection film may be used as a touch surface.

Description

technical field [0001] The invention relates to a capacitive touch element with a flexible shape or a three-dimensional shape, a manufacturing method thereof, and a capacitive touch detection device comprising the capacitive touch element. Background technique [0002] As input devices of electronic equipment, touch panels are used in various fields. The touch panel is composed of a touch element having a touch surface approached or contacted by a contact object such as a part of a human body (for example, a finger) or a pen tip, a control circuit unit that generates an electric signal corresponding to a touch position specified by the approach or contact on the touch surface, etc. constitute. In many cases, a touch panel is configured such that touch elements are disposed in front of an image display device, and a user determines a touch position based on a display image transmitted from the touch surface. In this case, the touch element must transmit light so that the di...
