Title:
CAPACITANCE SENSOR AND MANUFACTURING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2011/002025
Kind Code:
A1
Abstract:
Provided is a capacitance sensor and a manufacturing method thereof, wherein fear of malfunctioning or damages accompanying long-term use is eradicated, expansion in the installation space can be minimized, and contamination resistance against dirtiness such as dust can be increased. The capacitance sensor is provided with a pair of electrode bodies (1) that has conductivity, and an insulative dielectric manipulation body (21) that covers this pair of electrode bodies (1); functions as an input device by detecting changes in the capacitance when a finger touches this dielectric manipulation body (21); and is made to be electrically connectable to an electronic circuit, by processing each of the electrodes (1) into a three-dimensional shape with metallic materials. Furthermore, the dielectric manipulation body (21) is molded into a three-dimensional shape with molding materials including resin, and portions of the pair of conductive electrode bodies (1) are buried in integration inside the dielectric manipulation body (21). Since a capacitance sensor that is not mechanical is used, fear of malfunctioning or damages accompanying long-term use is expected to be eradicated, and manufacturing cost is also expected to be reduced.
