Abstract
A ballpoint pen bends at the pen tip, that can be changed by the force applied when writing. Wobbling does not occur, and a stable writing feel can be obtained. The ballpoint pen makes it possible to clearly change the thickness of the drawn line by the force applied when writing, so that lines of different thickness can be written with a single writing tip using the angle of the ballpoint pen tip. The ballpoint pen includes: a writing ball; a holder for holding the writing ball; an ink supply section; a shaft body inside which the ink supply section is held; and a tip shaft, which is connected to the tip of the shaft body and from which the holder protrudes during writing. The tip shaft is formed by two-color molding in which a front half and a back half are interdigitated in a saw tooth form.
