IDENTIFICATION COMPONENT, WRITING INSTRUMENT, AND HANDWRITING INPUT SYSTEM

The present disclosure provides an identification component, a writing instrument, and a handwriting input system that can decrease the cost by employing a simpler configuration. The identification component is attached to a pen and includes a resonance coil formed to have an external shape thinner than the writing instrument, an resonance circuit that outputs an identification signal used for identifying an attribute of the pen, and a holding member that holds the resonance coil close to one end of the pen where a pen tip is present to render the longitudinal direction of the resonance coil parallel to the longitudinal direction of the pen. 本发明的目的在于提供一种能够通过简易的结构谋求书写工具低成本化的识别符、书写工具、以及书写输入系统。被安装在笔的识别符，包括：谐振线圈，以比所述笔细的外形构成；谐振电路，输出识别与所述笔有关的属性的识别信号；以及保持部件，将所述谐振线圈在所述笔的前端附近以所述谐振线圈的长边方向朝向所述笔的长边方向的方式保持。
