Abstract: A stabilizer (10) disposed on a suspension mechanism part of a vehicle comprises a stabilizer bar (20) and a rubber bush (60). The stabilizer bar (20) includes a bar body (40) made of a steel material, and a coating film (41) coating the bar body (40). The coating film (41) is formed on the surface of the bar body (40) by using a resin having a water contact angle of more than 65 degrees. By performing surface treatment for reducing the contact angle of the coating film (41) present on an attachment part (20a), the contact angle of the attachment part (20a) is changed to 65 degrees or less. A pre-cured liquid adhesive agent (70) is applied to an inner surface (adhesion surface) (64, 65) of the rubber bush (60). After a region including the attachment part (20a) of the stabilizer bar (20) is heated by high-frequency induction heating or the like, the rubber bush (60) is overlaid on the attachment part (20a). Subsequently, the adhesive agent (70) is cured in a state where the rubber bush (60) is pressed.
