Input pen for touch panel, and input pen

摘要

An input pen for a touch panel excellent in a using feeling without causing any flaw in a display, and an input pen. A touch ball made of, for example, an acetal resin is provided at a pen tip of an input pen. The touch ball is held via a first spring and a second spring. Furthermore, respective spring constants of the first spring and the second spring are set in such a manner as to establish the relationship of (a displacement of the first spring)>(a displacement of the second spring)>(a deformation of the touch ball) when pressing force for pressing the touch ball toward a main body shaft acts. Thus, it is possible to suppress any deformation of the soft touch ball even if the input pen is strongly pressed against a screen of a touch panel or the like.
