  • Patent number: 10156915
    Abstract: A position pointing device includes a pressure detecting part which detects a pressure applied in an axial direction of a core body. The core body includes: a leading end part formed from an elastic material; a pedestal part which is formed from a material harder than the material of the leading end part and is joined to the leading end part; and a core body main body part which is joined to the pedestal part, is smaller than the pedestal part in thickness in a direction orthogonal to the axial direction, and is formed from a hard material. The core body is housed in a casing and is movable in the axial direction, such that the leading end part is exposed via an opening of the casing, and a pressure exerted on the leading end part in the axial direction is transmitted to the pressure detecting part.
