Abstract
A position detecting apparatus is provided with a detecting face so as to detect the positions of points specified on the detection face thereof, which is capable of the detection of the minute position with a detection resolution for the whole detection face being not made finer, because the detection resolution of the region in one portion of the detection face is made finer than the detection resolution of the whole detection face, whereby highly advanced manufacturing art is not required as compared with a case where the detection resolution of the whole detection face has been made finer, thus resulting in lower cost.
