PROBLEM TO BE SOLVED: To provide a ball chain in which an application area of a product is not restricted, and to provide a production method of a ball chain.SOLUTION: A ball chain includes a spherical component 2 and a connection component 1. The spherical component 2 is hollow, and is provided with insertion holes 2a respectively on facing spots on a peripheral wall enclosing a hollow part S. The connection component 1 has on both ends, engaging parts 1a to be engaged with an inner part of the peripheral wall by being inserted into the insertion holes 2a of the spherical component 2, respectively. The connection component 1 is formed by plastically deforming pipe members 20 and 21. |
