PROBLEM TO BE SOLVED: To surely anchor a tendon arranged outside a concrete member simply onto the concrete member, and to introduce prestress. SOLUTION: The anchorage device 3 is abutted and engaged to a surface rectangular to and parallel with the axis of the tendon 2 of the concrete member 1, and the tendon is engaged with the anchorage device and tensile force is introduced. The anchorage device has a main body section 11 composed of two steel plate materials connected at an interval, and the tendon is inserted between the two steel plate materials and engaged with a tendon anchor plate 12 by a nut 4. Projecting sections 11a to the sides are formed near end sections in the steel plate materials, bearing sections 14 installed to the projecting sections are abutted against the surface rectangular to the axis of the tendon, and force transmitted from the tendon is worked to the concrete member.
