Abstract
Provided is a wing structure comprising a wing body formed from fiber-reinforced plastic (FRP), and an erosion suppression layer provided so as to cover at least a portion of a front edge of the wing structure. The erosion suppression layer contains a thermal spraying layer configured so as to maintain, by having a prescribed surface roughness, a liquid film formed on the erosion suppression layer.
