Summary:In an anchorage (1) of continuous fiber-reinforced polymer (CFRP) strands that anchors continuous fiber-reinforced polymer strands (2) to concrete structures, there is provided an untwisted diameter-expanded portion (3) expanded to a diameter D2 by being radially expanded with respect to a diameter D1 of a general portion (4) of the CFRP strands (2) by untwisting any section of the CFRP strands (2) formed by stranding a plurality of element wires (20, 21) that are bundles of multiple continuous fibers, and filling and curing a time curable material (5) in a clearance among the element wires the untwisted section that is untwisted.
