Disclosed is a metal pipe (1) provided with a pipe main body (10), and a flange (20) which is provided on an end of the pipe main body (10) and which is to be fastened to another component. The pipe main body (10) is composed of a pipe member that is seamless in the axial direction. The central axis of one end of the pipe main body (10) is substantially perpendicular to the central axis of the other end when viewed from the side surface. The dimension of the pipe main body (10) in the longitudinal direction is less than five times the diameter of the pipe main body (10). A minimal curve portion (11) wherein the central axis is curved into an arc having a radius not larger than the diameter of the pipe main body (10), is provided in a part of the pipe main body (10). A large-diameter portion (13) is provided on one end of the pipe main body (10), so as to be eccentric with respect to the central axis of the intermediate portion of the pipe main body (10), said large-diameter portion having a larger diameter than the diameter of the other end. |
