PROBLEM TO BE SOLVED: To provide an anchor for seismic strengthening, capable of increasing a seismic strengthening performance and a seismic strengthening structure using the anchor. SOLUTION: A fixed shaft part 2 on which a male screw 6 is formed at least partly and which is screwed and fixed in a hole drilled in an existing structure through the male screw, and a fixing shaft part 3 which is formed of a material having a lower strength than the material of the fixed shaft and buried in a newly installed structure or an extended structure are formed integrally with each other. The strength of the fixing shaft is substantially equal to the strength of the fixed body provided to the extended structure and the strength of the reinforcements disposed in the newly installed structure.
