PROBLEM TO BE SOLVED: To provide an apparatus for coating and a method for coating in which a wire body passing through a quartz tube causes no shift of the wire, even though the flow rate of inert gas passing through the quartz tube is in creased, in applying the wire body such as an optical fiber, or the like, with a coating comprising an ultraviolet curable resin, the wire body having good appearance is obtained, clouding due to adhering of the volatile ingredient generated during hardening of the ultraviolet curable resin does not occur on the inner wall of the quartz tube, therefore, there is no need to cleaning. SOLUTION: In the coating apparatus applying the coating comprising the ultraviolet curable resin on the wire body 1 such as the optical fiber, or the like, the direction in which the inert gas blows out from an inert gas blowing out port 15 attached to the end portion of the quartz tube 2 in an ultraviolet curing zone and the traveling direction of the wire body 1 passing through the quartz tube 2 are substantially parallel, and the inert gas flowing in from the blowing out port 15 is adjusted not to impinge directly on the wire body 1.
