Provided is a chain of which a coating film has favorable adhesiveness and uniformity, and rust resistance is maintained over the long term. The chain (10) is provided with an inner plate (11), a bushing (12), an outer plate (13), a linking pin (14), and a roller (15). Each constituent component has: a zinc-aluminum-magnesium alloy coating film formed by means of mechanical plating on an iron-based substrate; and a coating film formed on the zinc-aluminum-magnesium alloy coating film using a water-based rust-resistant coating material containing zinc, barium sulfate, and colloidal silica. |
