<P>PROBLEM TO BE SOLVED: To provide a capacitance type sensor capable of performing a stable sensor function and excellent in durability and a method for manufacturing the same: in which non-conductive rubber or elastomer is used except in an upper face part of each of movable electrode parts split into a plurality of portions of a sensor for varying capacitance; in which the rubber or elastomer is prevented from being deformed due to repetitive processing while making use of the original characteristic of the rubber or elastomer, a positioning hole is formed in each of the central positions of sensor constituent members including a sensor substrate, displacement on an XY plane in a circumferential direction and the like is prevented, and an output voltage in each of split fixed electrode part areas is prevented from being deviated; and in which the sensor is housed in an inside in a state that the sensor is positioned at a central position of each sensor constituent member and the circumference of a keypad rubber disposed above the upper face of the sensor with an interval therebetween is formed to be a structure integrally fixed by a laser beam, thereby operability is excellent, restoration performance is improved, and an output signal can be detected in a stable state by using changes in capacitance to a force or acceleration change as an output voltage. <P>SOLUTION: A capacitance type sensor is configured in such a manner that a sensor substrate provided with fixed electrode parts circumferentially split into a plurality of portions, a sensor rubber in which a portion except movable electrode parts each provided in a position facing each of the fixed electrode parts is formed of a non-conductive rubber or a non-conductive elastomer, and a keypad rubber disposed above the upper face of the sensor rubber with an interval therebetween are positioned in regard of respective central parts, positioned in respective circumferential directions or on an XY plane in a rectangular direction, and integrally formed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
