PROBLEM TO BE SOLVED: To provide a sorter stably carrying out sieving work without causing clogging of a sieve in a sieving work of construction wastes and reliably removing stones with a prescribed size or larger, concrete blocks, excess soil, wood pieces, plastics, and cloths. SOLUTION: The three-dimensional sorter comprises a plurality of sieving faces made of a large number of finger-like projections which are fixed in a vibrator in one end and arranged in parallel. A plurality of the sieving faces are installed in such a manner that their projection drawings are overlapped one another: the sieving faces are at different positions in the vertical direction: and the finger-like projections of two neighboring sieving faces in the up and down direction are arranged so as to have main parts of their projection drawings which are not overlapped each other.
