To provide an anchorage device of a continuous fiber reinforced strand which does not use a member corresponding to a metal sleeve and has a low manufacturing cost as it can be manufactured in a construction site too and functions enough as an anchorage device.SOLUTION: In an anchorage device 1 of a continuous fiber reinforced strand for anchoring a continuous fiber reinforced strand 2 to a structure, by untwisting any section of a continuous fiber reinforced strand 2 formed by a plurality of strand (20,21) bundle of a multiple continuous fiber, filling a gap between strands in an untwisted section with a curing material 5 which cures with the passage of time, and curing the curing material 5, an untwisted enlarged diameter part 3 which is enlarged into a diameter D2 enlarged to be larger than a diameter D1 of a common part 4 of the continuous fiber reinforced strand 2 is arranged.SELECTED DRAWING: Figure 1 【課題】金属スリーブに相当する部材を使用せずに、施工現場においても製造可能なため製造コストが安く、定着具として充分に機能する連続繊維補強より線の定着具を提供する。【解決手段】構造物に連続繊維補強より線２を定着させる連続繊維補強より線の定着具１において、多数の連続繊維を束ねた素線（２０，２１）が複数本より合されて成形された連続繊維補強より線２の任意の区間を解撚して、解撚した解撚区間の素線同士の隙間に、経時硬化材５を充填して硬化させることにより、連続繊維補強より線２の一般部４の径Ｄ１より拡径させて径Ｄ２に拡大した解撚拡径部３を設ける。【選択図】図１
