An apparatus for fabricating three-dimensional nonwoven fabric structure is disclosed, which includes an adjustable frame, a three-dimensional mold, a rotary shaft connecting the three-dimensional mold and the adjustable frame, and a meltblown device. The three-dimensional mold is rotated relative to the adjustable frame. The meltblown device has plural nozzles for spinning a plurality of fibers, wherein the three-dimensional mold is rotated in front of the nozzles to select the fibers, and a three-dimensional nonwoven fabric structure is formed on the three-dimensional mold.
