An electric resistance welded steel pipe for manufacturing a hollow stabilizer has a Lankford value in a pipe longitudinal direction of from 0.7 to less than 1.0. The electric resistance welded steel pipe is subjected to cold bending and then to a heat treatment including quenching and tempering to manufacture a stabilizer. The cold bending is cold rotary draw bending. When bent with a bend radius of from 1.0 times to 3.0 times an outer diameter of the pipe before cold bending, a flattening ratio is from 0% to 10%, a thickness reduction rate on a bending outside and a thickness increase rate on a bending inside are from 0% to 10%, and additionally, a circumferential length change of a bending center portion is from 0% to 10%. A Vickers hardness of the stabilizer after the heat treatment is adjusted to from 400 HV to less than 580 HV.

Electric-resistance-welded steel pipe for producing hollow stabilizer, hollow stabilizer, and method for producing same

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 (&#x3b8;) 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&#xb0; or more and less than 180&#xb0;.
