PROBLEM TO BE SOLVED: To provide a down-pipe with an antenna for allowing the separation of the antenna from a rainwater drain channel and improving its workability even when manufactured. SOLUTION: A down-pipe 1 with an antenna includes a gutter body 11 formed by a cylindrical body and having the antenna 2 on the side wall of the cylindrical body, an inner cylinder body 12 provided inside the gutter body 11 for serving as a drain channel 120 through which rainwater flows, and a lower connector 5 for mutually connecting the lower end of the inner cylinder body 12 to the lower end of the gutter body 11. The lower connector 5 has a fitted part 54 to which the lower end of the inner cylinder body 12 is externally fitted, and a guide part 542 protruded upward on a part in the peripheral direction of the fitted part 54 for serving as a guide when fitting and connecting the inner cylinder body 12 to the fitted part 54.
