PROBLEM TO BE SOLVED: To provide a seismic strengthening construction method for an existing concrete bridge pier, which dispenses with the deep excavation of soil around a bridge pier or the formation of a cut-off wall, which can shorten a construction period, and which makes construction costs lower. SOLUTION: In this seismic strengthening construction method for the existing concrete bridge pier, a hole reaching stable ground is formed obliquely downward from the vicinity of the ground section of the existing concrete bridge pier or the outer peripheral section of the water-surface section thereof; a reinforcing member composed of a steel material, and a solidification material are infilled into the hole and solidified; and the other end of the reinforcing member is fixed to and integrated with the vicinity of the ground section of a bridge pier skeleton or the outer periphery of the water-surface section thereof.
