Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a mold repairing method which can make the mold after being repaired maintain cooling efficiency equivalent to that of the mold before being repaired, can sufficiently integrate the repairing member with the mold, and is low in cost. SOLUTION: The mold repairing method for repairing a hurt C generated in the cooling water passage of the mold 11 includes a silver solder pouring process for pouring silver solder 66 into the cooling water passage from its opening 14 side, a cooling/solidification process for cooling/solidifying the silver solder 66, and a hole forming process for boring a hole 77 for forming a new water passage in the solidified silver solder 66.
