Abstract
【解決手段】ペン先1を一端とする芯体2が、位置検出コイル3の巻かれた磁気コア4を貫通するように配設される。この磁気コア4は、軟磁性金属粉末を有機樹脂等のバインダーに混合した組成物を、例えば射出成形により成形した構造物により形成される。芯体2の他端には、ドーム状に形成された導電性弾性部材5が設けられ、その近傍に一方の面には所定の面積を有する電極7が設けられ、他方の面にはリード電極8が設けられた誘電体6が設けられる。さらに、電極7及びリード電極8からのリード線が回路基板9に接続される。また、位置検出コイル3からのリード線も回路基板9に接続される。以上の構成が外筐体10に収容されて位置指示装置が形成される。
