Patent ID: 7167420

Claim:
A timepiece comprising: a motor constituting a driving source, said motor including a rotor having a pinion section and a shaft section; a gear wheel configured so as to rotate by rotation of said rotor, said gear wheel having a gear wheel section and a shaft section; and a substrate including a bearing section which rotatably supports the shaft section of said rotor and/or the shaft section of said gear wheel, wherein said substrate is formed from a filled resin having a base resin of thermoplastic resin and carbon fiber mixed with this base resin, and said carbon filler is selected from a group consisting of: a monolayer carbon nanotube, a multilayer carbon nanotube, a nanografiber, a carbon nano horn, a cup stack type carbon nanotube, a monolayer fullerene, a multilayer fullerene, and a mixture of any one of the carbon fillers doped with boron.
