PROBLEM TO BE SOLVED: To provide a repairing material for an oven wall of a coke oven carbonization chamber that improves: a fill factor (fill depth into an inside of a crack) of the repairing material to fill, by blowing, a joint break or a crack failure generated in the oven wall of the coke oven carbonization chamber which partitions a combustion chamber and the carbonization chamber; and sealability (airtightness), as well as to provide a method of repairing the wall. SOLUTION: This repairing material includes a≥50% silica fine powder as a main component and has no sintering promoter except a metal, wherein preferably≤1% Si or Al or those mixture is added as the metal having reactive sintering behavior.
