<p>In a writing instrument having a vibrator in the core, variations in the state of the vibrator mounted on the core among individual are suppressed. A writing instrument (10) comprises a core (12) supported by an outer sleeve (16), and a pair of vibrators (20) disposed on the outer peripheral surface of the core (12) in opposed relation to each other with the center line (C) of the core (12) located therebetween. With such arrangement, since the plane of contact of the vibrators (20) with the core (12) is exposed outward, a more uniform adhesive agent layer can be formed when these are adhesively fixed, and variations in the mounted state of the vibrators (20) among individuals can be suppressed.</p> |
