Abstract
A grip using a gel substance capable of preserving its own shape is provided in a grip portion of a barrel of a writing implement. An outer coat for covering the grip portion of the barrel 1 is provided. The gel substance is located between the outer coat and the barrel, and comes in direct contact with the barrel. A centering member for positioning the outer coat coaxially with the barrel is provided between the outer coat and the barrel. The centering member is provided with an opening for allowing a space between the outer coat and the barrel to communicate with the outside of the space. The gel substance is formed by injecting a sol substance, which is a raw material, through the opening and by crosslinking the sol substance under a predetermined condition.
