Claim Text:
1. A pen-shaped coordinate indicator comprising: a core body that projects from one end of a chassis to form a pen tip; a columnar first magnetic body having a first end surface and a second end surface, the first end surface being in contact with the core body; a columnar second magnetic body having a first end surface opposite the second end surface of the first magnetic body; a coil wound around at least one of the first and second magnetic bodies; a capacitor connected to the coil; and an elastic body that is provided between the second end surface of the first magnetic body and the first end surface of the second magnetic body and is configured to be deformed when a pressing force is applied to the core body in an axial direction, wherein the elastic body is composed of a main body part and at least one projection extending outwardly from an external surface of the main body part, and the main body and the at least one projection are formed of the same material and form a continuous structure, the at least one projection contacts at least one of the second end surface of the first magnetic body and the first end surface of the second magnetic body; the main body part and the projection are arranged to position the first magnetic body and the second magnetic body to be separated from each other in a state in which the pressing force is not applied to the core body, and when the pressing force is applied to the core body, initially the projection is mainly deformed, and after the projection is deformed, the main body part is mainly deformed to thereby change a distance between the first magnetic body and the second magnetic body according to the pressing force applied to the core body.
