Abstract
An inexpensively-produced operating tool to which information about the direction of the operating tool or various kinds of identification information can be provided, and in which a switch can be provided. An operating tool (100), which is placed on the detection plane of a conductor detector capable of detecting a conductor by detecting a change in coupling coefficient of loop coil groups crossing each other, comprises a plurality of conductor pieces (102). The conductor piece has, for example, a circular shape, a rectangular shape, or a ring shape. At least a part of the plurality of conductor pieces may be arranged in a predetermined pattern such that the conductor detector can detect the direction of the operating tool.
