1. A laminate material for reinforcement bonded to and integrated with a surface to be reinforced of a structure to reinforce the structure, the laminate material for reinforcement of the structure having:
a fiber-reinforced composite member; a high-elongation elastic resin layer formed on a surface on a bonding side to the structure of the fiber-reinforced composite member; and an intermediate resin layer disposed between the fiber-reinforced composite member and the high-elongation elastic resin layer, wherein the intermediate resin layer has a tensile elasticity when cured of 1000 N/mm2 or more and 10000 N/mm2 or less, and wherein the intermediate resin layer has a thickness of 0.05 mm or more and 5.0 mm or less.
