PROBLEM TO BE SOLVED: To provide a vibration-control reinforcing structure for an existing building, which avoids increase in the mass of the building, and does not reduce an effective space of the building. SOLUTION: In formation of the vibration-control reinforcing structure, slits are formed at boundaries between an existing wall 12 and columns on both sides of the same to isolate the former from the latter, and another slit 16 is formed at a boundary between the existing wall 12 and an upper-story beam 13 to isolate the former form the latter, to thereby make the existing wall 12 into an independent structure. Then a one-side upper edge of the existing wall 12 and a one-side lower edge of the upper-story beam 13 which are flush with each other, are diagonally cut away at 45 degrees in a longitudinal section to form a triangular notch 17, and after leveling formed slant surfaces 12a, 13a with mortar 18, a panel damper 11 is secured to the slant surfaces 12a, 13a by means of anchor bolts 19.
