Abstract

There are provided an electric resistance welded steel pipe for producing a high strength hollow stabilizer excellent in fatigue resistance and a high strength hollow stabilizer. In an electric resistance welded steel pipe () for producing a hollow stabilizer, an internal weld bead cut portion () has a three-peak shape and a depth (H) of a trough portion () of the three-peak shape is 0.3 mm or less and an angle (θ) formed by a central portion in the circumferential direction of the trough portion () and the top of right and left peak portions () located on both the right and left sides of the trough portion () is 160° or more and less than 180°.
