PROBLEM TO BE SOLVED: To provide a method for cooling a hot-rolled steel strip by which the accuracy of the coiling temperature in the length direction of the hot-rolled steel strip is suppressed from lowering and temperature deviation in the width direction of the hot-rolled steel strip is reduced even in the case that the steel strip is wide and the coiling temperature is low. SOLUTION: Side sprays which are arranged closely to the downstream side of the water cooling banks located on the most downstream side among the side sprays installed in a plurality of places in the length direction of cooling equipment in accordance with the number of the water cooling banks are jetted, and the jetting of the side sprays arranged on the upstream side of the water cooling bank located on the most downstream side and in a water-injecting cooling zone is stopped.
