PROBLEM TO BE SOLVED: To provide a writing instrument barrel that is superior in material strength, workability and appearance, even if using wood impregnated with a synthetic resin in a writing instrument barrel using the wood, and can prevent cracks in machining and breakage when dropped, and also is superior in dimensional stability and can prevent cracks, deformation or operational failures due to dimensional change after being assembled in writing instruments.SOLUTION: As a writing instrument barrel comprising wood impregnated with a synthetic resin, a specific gravity under oven-dry of the wood before the impregnation is determined in a specific range. |
