摘要： A stabilizer including: a main body for generating an elastic restoring force; and connecting portions formed on both ends of the main body and respectively connected to left and right suspension devices. Hardness of the connecting portions is lower than that of the main body. A method for manufacturing the stabilizer includes, in order, an entire body heat treatment process for heat treating an entire stabilizer and increasing hardness of the entire stabilizer, and a connecting portion softening process for heating the connecting portions and reducing the hardness of the connecting portions. The method for manufacturing the stabilizer thereby increases hardness of the main body and reduces the hardness of the connecting portions lower than that of the main body.
