ABSTRACT:
A capacitive rotational position detecting apparatus includes a stationary disk plate and a rotatable disk plate in opposite relation. The stationary plate has a first and a second electrode on one surface, each of which is electrically connected through apertures by a metal film formed on the other surface of the stationary plate to reduce a distribution capacitance formed between metal films of the stationary and rotatable plates.
