A hollow stabilizer (1) according to the invention is formed in a hollow shape and includes a bent portion (1c1, 1c2, m1-m5). With a thickness of an inner side of the bent portion (1c1, 1c2, m1-m5) being larger than a thickness of an outer side of the bent portion (1c1, 1c2, m1-m5), a hardness of the outer side of the bent portion (1c1, 1c2, m1-m5) is higher than a hardness of the inner side of the bent portion (1c1, 1c2, m1-m5) through quenching by cooling down after heating by electrical heating.
