Abstract: Disclosed herein is a sectional three-dimensional model, which can be assembled by use of an independent single type of pieces without requiring several kinds of pieces having different shapes from one another, and achieve a three-dimensional connection of the pieces. The sectional three-dimensional model includes a plurality of spherical pieces, and each spherical piece includes a pair of coupling recesses symmetrically formed in the spherical piece along a center axis of the spherical piece, and a plurality of coupling protrusions integrally formed at an outer surface of the spherical piece to be arranged in directions perpendicular to the coupling recesses, thereby allowing the plurality of spherical pieces to be connected to one another via insertion of the coupling protrusions into the coupling recesses.
