Abstract:
To provide a jumper structure which is light-weighted and capable of reducing fabrication cost and a timepiece using the same. A jumper structure of a timepiece is constituted by integrally molding a jumping and restricting portion made of carbon nanofiber and a spring portion made of carbon nanofiber. A jumping and restricting portion of the jumper structure is thicker than the spring portion and the jumping and restricting portion includes a projected portion in a flat plate shape and in an eaves-like shape.
