PROBLEM TO BE SOLVED: To provide an air spoiler integrally formed by blow molding improved in rigidity or strength, capable of retaining satisfactory appearance design property and aerodynamic performance regardless of the mounting position to a body. SOLUTION: This thermoplastic resin-made air spoiler 1 manufactured by blow molding and mounted on a vehicle 2 is formed of a hollow spoiler body part 11 extending in the lateral direction and a lengthy plate-like solid continued part 12 extending along at least one edge of the spoiler body 11 and integrally continued thereto. Stepped parts 25 and 25' descending from the solid continued part 12 toward the spoiler body part 11 are provided in the boundary part between the spoiler body part 11 and the solid continued part 12. The surface is never dropped, and the reinforcement of the inner part of the spoiler body part 11 with a plate rib is dispensed with.
