ABSTRACT:
A flap type handle equipped with an electrostatic capacitance sensor, in which sensitivity adjustment can be easily performed without changing the specification of a sensor body3, reduces the difference in detection sensitivity with respect to the position and perform required balance adjustment. A sensor body is fixed to a handle base portion. The detection face of the sensor body is oriented to a predetermined detection range at the inner surface side of a hand flap. An electrically conductive face is provided to the inner surface of the handle flap so as to cover the detection range. A connecting electric conductor for electromagnetically couple the electrically conductive face and the detection electrode at least under the non-operation of the handle flap is provided. The connecting electric conductor or/and the electrically conductive face are subjected to detection sensitivity adjusting trimming (provided with a cut-out or the like).
