Hairspring structure and speed control mechanism for timepiece

摘要

To provide a hairspring main body having small variation in weight distribution when in an inclined state and little influence from static electricity or external magnetic field, a hairspring structure capable of being easily integrated accurately. A hairspring structure (30) of a speed control mechanism (2) of a movement (1) includes a hairspring main body (40) made of carbon nanofiber and a hairspring attaching portion (3) made of carbon nanofiber integrally molded with the main body, coupled to one end portion of the main body and substantially rigid.
