PROBLEM TO BE SOLVED: To provide a cooling apparatus and method of a hot rolled steel strip capable of giving appropriate feeding force to a hot rolled steel strip on a hot-run table located at an outlet side of a finish rolling mill and securing a stable traveling property of the hot rolled steel strip. SOLUTION: In an apparatus cooling a hot rolled steel strip fed on the hot- run table which is arranged at the outlet side of the finish rolling mill, the cooling apparatus of the hot rolled steel strip is characterized in that the apparatus is provided with a lower cooling means arranged between feeding rolls comprising the hot-run table and feeding a coolant on a lower face of the hot rolled steel strip traveling on the hot-run table, an upper cooling means arranged at a position not opposing to the lower cooling means in an up and down direction at an upper position of the hot-run table and feeding a coolant on an upper face of the hot rolled steel strip traveling on the hot-run table, and a coolant damming means approached to the hot rolled steel strip and arranged along a widthwise direction of the steel strip so that the flow of the coolant to a longitudinal direction of the hot rolled steel strip fed from the upper cooling means is controlled.
