Abstract
A pressurized writing implement includes a shaft tube capable of housing therein a refill filled with a writing implement ink composition. The pressurized writing implement further includes a pressurizing mechanism that applies a pressure to the writing implement ink composition, the pressurized writing implement being capable of switching a writing state in which a front end part of the refill projects from a front end opening of the shaft tube, and a not-writing state in which the front end part of the refill is retracted from the front end opening of the shaft tube. The pressurized writing implement further includes a pressurizing-force adjusting mechanism that adjusts the pressure.
