PROBLEM TO BE SOLVED: To provide a coating structure of a connection part of a resin-coated steel tube and a coating method and a coating device for the connection part of the resin-coated steel tube hardly corroding and hardly peeling off or damaging, for example, when the resin-coated steel tube is propelled in the ground to bury it in the ground in a non-open cut construction method. SOLUTION: In this coating structure of the connection part of two or more steel tubes, its outer peripheral surface other than the end parts is covered with a resin layer. The structure comprises a resin film joined to the outer peripheral surface of the resin layer so as to surround the connection part and a sealing material disposed in a space formed by the outer peripheral surface of the steel tubes, the resin layer, and the resin film.
