A stabilizer includes a stabilizer main body, and eyes formed on both ends of the stabilizer main body. Through-holes are formed in fastening surfaces of the eyes, respectively. The stabilizer main body is covered with a main body coating film. The eye is covered with an eye coating film whose thickness is less than a thickness of the main body coating film. An inner surface of the through-hole is covered with an inner surface coating film. An incomplete coating portion is formed at a part of the inner surface of the through-hole in a circumferential direction. The incomplete coating portion is located on an extension of a straight line connecting a center of the through-hole and the center of gravity of the stabilizer main body in a side view of the stabilizer main body.
