At least one of the front and back ground structures of the three-dimensional knitted fabric has an uneven pattern with projections and depressions having a great level difference. Ground yarns of the at least one ground structure are traversed by a predetermined traverse width so that the projections each have a curved shape having a distinct curvature in section, and cast off at predetermined intervals so that the depressions each have an opening.
