Abstract
With magnetic poles of a magnetic scale each having a length in the moving direction of T, a magnetic field sensing part has m element lines (m≧2) each including n magnetic sensors (n≧2) as the magnetic sensors corresponding to one of the magnetic poles. The n magnetic sensors included in one of the element lines are arranged at a constant pitch of λ(λ=T/n). Each of the magnetic sensors included in the second or further element line is placed shifted by λ/m in the moving direction of the opposite magnetic pole from each of the magnetic sensors included in the previous element line.
