To provide a method for coating a spring member, efficiently baking a thermosetting coating material adhering to the spring member and capable of forming a coating film superior in adhesion and surface properties.
A method for coating a spring member comprises: a coating step in which a thermosetting coating material is applied to the surface of the spring member 10, thereby forming, in the spring member 10, a coated portion 20 having an uncured coating film 200 and two uncoated portions 21a, 21b arranged so that the coated portion 20 is positioned therebetween and not having the uncured coating film 200; an electrode connection step in which first electrodes 41a, 42a and second electrodes 41b, 42b are electrically connected to the two uncoated portions 21a, 21b, respectively; and a baking step in which the coating film 200 of the coated portion 20 arranged between the two uncoated portions 21a, 21b is baked by applying a voltage between the first electrodes 41a, 42a and the second electrodes 41b, 42b, thereby heating the spring member 10 by means of electrical conduction.
