PROBLEM TO BE SOLVED: To provide a method for cooling a steel material uniformly in its longitudinal direction. SOLUTION: In this method for cooling the steel material by vibrating the steel material in the horizontal direction or vibrating a cooling apparatus in the horizontal direction, the moving amount of the oscillation is controlled to satisfy an inequality ä(N+0.5)×P<L<(N+0.9)×P <L<SB>0</SB>-L<SB>k</SB>, wherein P is nozzle pitch in the cooling apparatus, N is positive integral number containing, L<SB>o</SB>is length of the cooling apparatus and L<SB>k</SB>is length of the steel material}.
