PROBLEM TO BE SOLVED: To provide a continuous casting mold having a long life by suppressing and preventing a crack from being caused by thermal stress induced by a cyclic load. SOLUTION: This continuous casting mold comprises a pair of short-piece members disposed opposite to each other with a space therebetween, a pair of long-piece members 10, 11 disposed opposite to each other in such a state that the short-piece member is held from both sides in the widthwise direction, and support members 13, 14 fixed to the backside thereof by fastening means 12, 12a. Cooling water is allowed to flow from a water supply part 15 in the lower part of the support members 13, 14 through a water passage part 16 on the backside of the short-piece members and the long-piece members 10, 11 into a water discharge part 17 on the upper part of the support members 13, 14. While cooling and solidifying a molten steel supplied into a region defined by the short-piece members and long-piece members 10, 11, the molten steel is drawn out downward to produce a cast strip. A thin flat plate is adopted in at least the upper side of the cooling member formed of one or both of the short-piece members and long-piece members 10, 11. COPYRIGHT: (C)2008,JPO&INPIT
