PROBLEM TO BE SOLVED: To provide a machine component capable of excellently driving a driving component without generating a crack with respect to a brittle material-based component such as silicon, and provide a manufacturing method of the machine component and a timepiece.SOLUTION: A driving component is attached to a machine component 126 by driving. The machine component includes: a base component 126g made of a brittle material such as silicon, having an open hole 126k; and an electroformed component 126h fixed to one surface of the base component 126g, having a diameter on the same axis as the open hole 126k and smaller than the open hole 126k, and having a holding hole 126j to which a driving component 126f is driven.SELECTED DRAWING: Figure 5 |
