Abstract
A wing unit is used in a wing flapping apparatus to perform a swinging motion to thereby generate levitation force. The wing unit includes a nonwoven fabric that forms a wing surface; a frame body overlaid on the nonwoven fabric and extending along the wing surface; and a resin material disposed in a cavity included in the nonwoven fabric to integrate the nonwoven fabric and the frame body with each other. According to this configuration, a light-weight and high-strength wing unit that produces a suppressed wing flapping noise, a wing flapping apparatus including the wing unit, and a method of manufacturing the wing unit are provided.
