Rare technical term; in modern Japanese, ハイパーリンク is overwhelmingly preferred. This kanji form may appear in older or highly formal computing contexts.
The term 超連結子 is used in this document, but nowadays it is normal to say ハイパーリンク.
A Japanese-coined kanji compound from 超 (chō, 'super') + 連結 (renketsu, 'connection') + 子 (shi, 'element'), likely created as a direct translation of 'hyperlink'. The exact origin is uncertain; it is now largely obsolete.
