Abstract
A pen-shaped coordinate indicator is provided, which is capable of preventing erroneous detection of the pressing force (writing pressure) and widening the detection range of the pressing force. The indicator includes a core body that forms a pen tip; a columnar first magnetic body having one end in contact with the core body and having another end opposing a columnar second magnetic body; and an elastic body provided between the first and second magnetic bodies. The elastic body is composed of a main body and at least one projection provided thereon, wherein the projection has a smaller resistance to the pressing force applied to the core body than the main body. When the pressing force is applied, initially the projection is mainly deformed, and thereafter the main body is mainly deformed to thereby change a distance between the first and second magnetic bodies according to the pressing force device.
