A rod for a coating device, used when a continuously-running body is coated with a coating solution, includes: a columnar base material; and an abrasion-resistant coating formed on a circumferential surface of the base material. When a friction coefficient between the coating and the body is represented by mu, a Vickers hardness of the coating is represented by Hv, a thermal expansion coefficient of the base material is represented by alpha<1>*10<-6>/DEG C, a thermal expansion coefficient of the coating is represented by alpha<2>*10<-6>/DEG C, and a film thickness of the coating is represented by t mum, mu and Hv satisfy a predetermined relational expression, and/or alpha<1>, alpha<2> and t satisfy another predetermined relational expression. Specifically, Hv>1500*mu<2>+1200 and/or |alpha<1>-alpha<2>|<3/(t-4)+7. The invention provides a process for producing a rod, for a coating device, on which an abrasion-resistant coating is formed on the circumferential surface of a column base material. |
