PROBLEM TO BE SOLVED: To provide a hot-rolling method by which piling-up of the rear end part of a preceding metal strip and the distal end part of a following metal strip can surely be controlled. SOLUTION: In the hot-rolling method, a joining apparatus 3 for joining the rear end part of a preceding metal bar 9 and the distal end part of a following metal bar 6 during running of the metal bar is arranged at the upstream side of the finish-mill 4 and at the same time, the rear end part of the preceding metal bar 9 and the distal end part of the following metal bar 6 are positioned at a joining position and also, the speeds of the preceding metal bar 9 and the following metal bar 6 are made almost the same, and in this state, the joining is completed in the joining apparatus 3 and thus the pile-up of the rear end part of the preceding metal bar 9 and the distal end part of the following metal bar 6 can surely be controlled.
