PROBLEM TO BE SOLVED: To provide a welded eaves gutter which is assembled by resin-welding without using a gutter joint or an adhesive at all, and exhibits a good appearance at a joint portion, and to provide a welding method for welding the eaves gutter with good workability and a welding material fitted for the method. SOLUTION: The welded eaves gutter 10 consists of a plurality of eaves gutter sections 1, 1 each formed of a synthetic resin, which are butted against each other via their edges and resin-welded together by the thermoplastic resin welding material 2 from inside the butted edges. The welding material 2 is formed by embedding a heating wire 22 in a banded body 21 formed of the thermoplastic resin, which is bent along inner end faces of the respective eaves gutter sections 1, 1, and drawing terminals 23, 23 for energizing the heating wire from the banded body 21. The welding method is carried out by superposing the welding material 2 on the inner end faces of the eaves gutter sections 1, 1 butted against each other, energizing the heating wire 22 to melt the banded body 21 formed of the thermoplastic resin, to thereby connect the eaves gutter sections 1, 1 together.
