noun
Refers to a pen-shaped input device for touchscreens, tablets, or graphics tablets. Also used for the needle of a record player, though that is less common in everyday contexts.
タブレット用のスタイラスを買った。
I bought a stylus for my tablet.
このスタイラスは細かい線が描きやすい。
This stylus makes it easy to draw fine lines.
タッチペン is a more general term for any pen-shaped touchscreen tool, while スタイラス often implies a more precise, active stylus for drawing or writing.
Borrowed from English 'stylus'.
