PROBLEM TO BE SOLVED: To provide a wet temper rolling mill and a wet temper rolling method, in particular a wet temper rolling mill and a wet temper rolling method for stably producing a product which has a low elongation percentage and has not been heretofore producible because of the occurrence of jumping. SOLUTION: The wet temper rolling mill composed of one or two rolling stands and performing temper rolling of a metal strip material 1 in which upper and lower yield points are present or a rolling method using the same is characterized in that equipment for imparting bending deformation or stretch deformation to the metal strip is arranged at the upstream of the wet temper rolling mill, and uniform plastic deformation is imparted to the metal strip at least in the longitudinal direction and the width direction. It is desirable that a roller leveller or a tension leveller is used as the equipment arranged at the upstream of the wet temper rolling mill, the relational expression expressing the relation between the quantity of working therein and the elongation percentage in the start of jumping in the wet temper rolling mill is obtained, and the quantity of working in the equipment arranged at the upstream of the wet temper rolling mill is controlled.
