The technology according to the present invention provides a delivery pipe (10) in which a valve attachment (40) is connected to a pipe at an offset position and strength of the pipe is maintained. The delivery pipe includes a pipe (20) integrally including at least one cylindrical tube section (22) and at least one flat tube section (24) , and a valve attachment including a hollow cylindrical portion (40b) and a connection portion (40a) having a planar shape. The flat tube section (24) includes a planar attachment portion having a distribution hole (24a1) extending through the planar attachment portion in a thickness direction thereof. The hollow cylindrical portion has a closed end closed by the connection portion and is configured to be attached to a fuel injection valve (60). The connection portion has an introduction hole (40a1) that extends through the connection portion in a thickness direction thereof and communicates with the distribution hole (24a1) of the planar attachment portion. The valve attachment is connected to the planar attachment portion at a position adjacent to one of edges of the planar attachment portion. The edges extend along an axial direction of the pipe.
