PROBLEM TO BE SOLVED: To realize a tireless ball-point pen of a soft writing touch by a method wherein a flexible 'bending ceramic' is used as a ball at a core tip of the ball-point pen instead of a hard writing touch because of a metallic ball at the core tip of the ball-point pen. SOLUTION: 'Bending ceramic' is used as a ball at a core tip of a ball-point pen. Since 'bending ceramic' is flexible ceramic when 'the bending ceramic' is used thus as the ball at the core tip, when a character or the like is written on paper, a smooth soft writing touch ball-point pen is obtained because of the elasticity of 'the bending ceramics'. |
