PROBLEM TO BE SOLVED: To provide a repair or reinforcement method which can significantly omit a repair or reinforcement work of a target structure and perform the work in a short time, and a tacky adhesive sheet for repair or reinforcement used in the same.SOLUTION: A method of repairing or reinforcing a target structure using a tacky adhesive sheet 10 comprises the steps of: preparing the tacky adhesive sheet 10 including a tacky adhesive layer 2 and a repair or reinforcement member 3; starting hardening of the tacky adhesive layer 2 by irradiating the tacky adhesive sheet 10 with an ionization radiation; and sticking the tacky adhesive layer 2 to the target structure after starting hardening. It is preferable that hardening of the tacky adhesive sheet 10 after sticking to the target structure progresses at a normal environment temperature of the target structure, and the repair or reinforcement member 3 is included in the tacky adhesive layer 2 or provided on one surface of the tacky adhesive layer 2. 【課題】対象構造物の補修又は補強作業を大幅に省略化でき、且つ短時間で行うことができる補修又は補強方法、及びその方法に用いる補修又は補強用粘接着シートを提供する。【解決手段】粘接着シート１０を用いて対象構造物を補修又は補強する方法であって、粘接着層２と補修又は補強部材３とを備えた粘接着シート１０を準備する工程と、粘接着シート１０に電離放射線を照射して粘接着層２の硬化を開始させる工程と、硬化を開始した後、粘接着層２を対象構造物に貼り合わせる工程とを有する方法によって上記課題を解決する。このとき、対象構造物に貼り合わせた後の粘接着シート１０の硬化が対象構造物の通常環境温度で進行し、補修又は補強部材３が、粘接着層２の内部に含まれている、又は粘接着層２の一方の面に設けられていることが好ましい。【選択図】図１
