Abstract

A position indicator comprises: a first indicator pattern composed of a plurality of substantially identical first partial patterns periodically arranged in a direction of extension, and a second indicator pattern composed of a plurality of substantially identical second partial patterns periodically arranged in the direction of extension. The first partial patterns may extend, along a first line extending transversely to the direction of extension, and the second partial patterns may extend along a second line extending transversely to the first line and the direction of extension The first and second partial patterns may be each composed of plural sub-patterns disposed adjacent to one another in the direction of extension. The sub-patterns of each pair of sub-patterns of the respective partial pattern are different from each other.
