A stray current Is is generated. Initially, currents I1 and I2 are equal to current Is ’, i1+I2=Is. Referring to FIG. 4B, when an object (such as a finger) touches point A, a capacitor 420 and a resistor 425 can be connected in series to equate the object, so that there is a current Ibi from the voltage source 4 and a current source 484. Current & flow to the object. At this time, the current supplied from the current source 482 becomes 1 ’’=^+]^, and the current supplied by the current source 4 becomes I2+IB2.
