1. A position indicator, comprising:

  • a cylindrical chassis;

    a core body, which is disposed within the cylindrical chassis such that a tip thereof protrudes from a distal opening end of the cylindrical chassis;

    a printed wiring board, which is disposed within the cylindrical chassis and which is provided with a circuit element to detect a pressing pressure applied to the tip of the core body;

    one or more pressure-sensitive components configured to detect a displacement of the core body, in an axial direction of the cylindrical chassis, corresponding to the pressing pressure applied to the tip; and

    a holder, which is accommodated within a hollow portion of the cylindrical chassis with its longitudinal direction being aligned with the axial direction of the cylindrical chassis,wherein the holder includes;

    a core body engaging portion configured to hold the core body and to regulate movement of the core body in a direction toward the tip;

    a component disposing portion, which defines an opening portion that opens in a direction perpendicular to the axial direction and in which the one or more pressure-sensitive components are arranged in the axial direction so as to receive the pressing pressure applied to the core body; and

    a printed wiring board mounting portion, which is engaged with the printed wiring board to mount the printed wiring board thereon with a longitudinal direction of the printed wiring board being aligned with the axial direction, andwherein the holder that secures therein the core body, the printed wiring board, and the one or more pressure-sensitive components is accommodated in the cylindrical chassis, whereby the pressing pressure applied to the core body is received by the holder to prevent the pressing pressure from being directly applied to the cylindrical chassis.
